Variables - the unknown value.

Have you ever wondered why children have different heights? Some children grow taller and some end up being shorter than average. To answer this question Scientists have come closer and researched the parameters in the form of variables that are the cause of height.

The word ‘variable’ is derived from the word ‘vary’ which means changing. Therefore, a variable can be any trait, condition, or factor that can change by only differing amounts or it is the unknown term whose value is not known. Example: A child’s height is dependent on the amount of protein and nutrients he or she consumes. Not only that, the height of kids is also dependent on their DNA which means if their parents are tall then there are more chances of them being tall whereas short parents usually have short kids. The height of the kid is also dependent on the rate of work or activities. It is believed that children with more activities like jumping, running, skipping, etc tend to grow faster. Thus, nutrients, DNA, and activities are the three variables that control the height in our body. These variables keep changing from body to body.

For example, while cooking dal we know that the quantity of water is thrice the number of lentils. That you can add 1 cup of lentils to three cups of water. This process can be expressed as,

Here, the quantity of lentils is variable. That means if the quantity of lentils changes then the quantity of water also changes.

In a World Full of Variables, You Will Always Find Constant.

There is one interesting thing about constants and that is this it never changes. A constant is actually a value that is a fixed number on its own. For example - In the equation 9 - x = 5, 9 and 5 are two constants whose values will not change whereas the value of x is not known. Thus, x is a variable.

Can Constant be a Coefficient To?

Since now we already know about variables, it is easier for us to understand the constant and coefficient. A coefficient is usually the number that is multiplied by the variable or letters. For example in ‘5x + y - 7’, 5 is a coefficient of x in the term 5x because it is a number that is multiplied by the unknown variable x. Also, in the term y, it can be considered as the coefficient of y because y can be written as 1xy.

The coefficient is the number that is always multiplied by the variables but constants are terms without variables. Therefore, coefficients cannot be called constants and vice versa. In the aforementioned example, -7 is constant.

Like terms are the terms having the same variables raised to the same power. In 5x + y - 7, no variable is common therefore no like terms. 

In 5a + 2b - 3a + 4 the terms like 5a and -3a are like terms whereas 4 is constant.

What is a Polynomial?

The word Polynomial is derived from the word poly ("many") and nominal ("term"). It is an expression consisting of many terms such that each term holds at least one variable. The variables can be raised to the power and further multiplied by a coefficient but the simplest polynomials hold one variable. The terms are separated by signs( + or - ). Also, the variables and numbers can be combined using addition, subtraction, multiplication or division but it can never be divided by a variable which means a term can never be like  2/x. A polynomial can also not have infinite terms. It always has a finite sum of terms with all variables having whole-number exponents and no variable as a denominator.

Polynomials are composed of the following:

Constants such as 3, −20, or ½, etc.

Variables such as g, h, x, y, etc.

Exponents such as 2 in y 2 or 5 in x5  etc

Examples of Polynomials: 5x 3 – 2x 2 + x – 13 and  x 2 y 3 + xy.

Degree of a Polynomial

It is simply the highest of the powers or exponents on the terms present in the algebraic expression.

Example: In 7x – 5, the first term is 7x, whereas the second term is -5. The power on the variable of the given first term is one and on the second term is zero. Since the highest exponent is one, the degree of the polynomial is also 1.

Types of Polynomials

Polynomials can be classified on the basis of

Number of Terms.

Degree of a polynomial.

Classification on the Basis of Terms

A polynomial either has one term, two terms, three terms, or more than three terms.

Monomials- ‘Mono’ stands for one and ‘mial’ stands for terms thus an algebraic expression with one term is called a monomial. 

Binomials- ‘Bi’ stands for two and ‘mial’ stands for terms therefore an algebraic expression with two, unlike terms is called binomials. 

Trinomials- ‘Tri’ stands for three and ‘mial’ stands for terms thus an algebraic expression with three unlike terms is called trinomials.

Classification on the Basis of Degrees

The Degree of Polynomial is considered as the highest value of the exponent in the expression because it is the largest exponent. We can also call it an order of the polynomial. While finding the degree of the polynomial, remember that the polynomial powers of the variables must be either in an ascending or descending order.

Linear Polynomial: If the expression holds degree 1 then we can call it a linear polynomial. 

Quadratic Polynomial: If the expression holds degree 2 then it can be called a quadratic polynomial.

Cubic Polynomial: If the expression holds degree 3 then it will be called a cubic polynomial.

Zeros of Polynomials

If the value of every coefficient of a variable is zero then it is called the zeros of a Polynomial. In order to find the relationship between the zeroes and coefficients of a given quadratic polynomial, we can find the zeros of the polynomial by the factorization method that is, by taking the sum and product of these zeros.

Operations on Polynomial

There are four main polynomial operations which are:

Addition of Polynomials

Subtraction of Polynomials

Multiplication of Polynomials

Division of Polynomials

FAQs on NCERT Solutions for Class 9 Maths Chapter 2 - Polynomials

1. What is Polynomial and How is It Classified on the Basis of the Number of Terms and Degrees ? 

A polynomial in a variable x is an algebraic expression  of the form

p(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + . . . . .+ a₂x²+ a₁x + a₀ ,where a₀, a₁, a₂, . . . . ., aₙ are constants and aₙ ≠ 0.

In the above expression of  polynomial p(x),  a₀, a₁, a₂, . . . . ., aₙ are respectively the coefficients of variables  x⁰, x, x² , . . . . ., xⁿ, and the degree of polynomial p(x) is the non-negative (i.e. n 0) power n to which the variable x is raised in the expression.

Each of the expressions aₙxⁿ + aₙ₋₁xⁿ⁻¹ + . . . . .+ a₂x²+ a₁x + a₀  is called terms of the polynomial p(x).

Polynomial class 9 are classified on the basis of the number of terms and degrees they have as follows:

Classification of Polynomials Based on the Number of Terms:

Monomial: A polynomial having only one term is known as a monomial.

Example: 2x², – 3,  –3/2 (y) 

Binomial: A polynomial having two terms is known as a binomial.

Example: 2x² + 1, x – 3,  –3/2(y) + x

Trinomial: A polynomial having three terms is known as a trinomial.

Example: x² - 2x + 2

Classification of Polynomials Based on the Degrees of Its Variable:

Linear polynomial: A polynomial having degree one is known as a linear polynomial. 

Example: 2x + y, x – 3

Quadratic polynomial: A polynomial having degree two is known as a quadratic polynomial.

Example: 2x² + 1, x² - 2x + 2

Cubic polynomial: A polynomial of degree three is known as a cubic polynomial.

Example: x³ + 4x² + 7x - 3

2. Give the Difference between Remainder and Factor Theorem?

The remainder theorem states that if a polynomial p(x) is divided by (x - a), then the remainder is obtained by evaluating the expression p(a).

While, the Factor theorem states that (x - a) will be a factor of polynomial p(x) only if the remainder obtained by evaluating the expression p(a) equals zero i.e; p(a) = 0.

For Example: let p(x) = x² - 6x + 9, then find the remainder when it is divided by (x - 1).

So, according to the remainder theorem, remainder is obtained by evaluating the expression p(1)

p(1) = 1² - 6(1) + 9 

       = 1 - 6 + 9 = 4.

Therefore, the remainder is 4 when  p(x) = x² - 6x + 9 is divided by (x - 1).

Now, check whether (x - 3) is the factor of p(x) = x² - 6x + 9.

So, according to factor theorem  (x - 3) is the factor of p(x) = x² - 6x + 9 only if p(3) = 0.

p(3) = 3² - 6(3) + 9

        = 9 - 18 + 9 = 0.

Therefore,  (x - 3) is the factor of p(x) = x² - 6x + 9.

3. What is an Algebraic Identity and What are Its Uses?

An algebraic identity is an algebraic equation that is true for any values of the variables occurring in it.

Algebraic identities are used to factorize the algebraic expressions and to compute the products of some arithmetic expressions without multiplying them directly.

Most commonly used algebraic identities are, (a + b)² = a² + 2ab + b² and (a - b)² = a² - 2ab + b², etc.

4. What are Polynomials in One Variable?

Polynomials are algebraic expressions in which variables and constants terms are connected by various arithmetic operators. For ‘Polynomials in one variable’ the terms of the polynomial have the same common variable, with numeric coefficients. In ‘Polynomials in one variable’, the variables are raised to powers and the degree of the equation can be determined with the highest power of the variable. Also, the degree of a polynomial is always a positive integer. Hence, if there is a variable term raised to a negative power in an algebraic expression, then it is not counted as a polynomial.

Examples of Polynomials: 2x³ - 7x² + 3x - 2, in this algebraic expression, there are four terms, and all the variable terms have positive integer exponents. So, this algebraic expression is a polynomial.

5. What do We Learn in the Class 9 Maths Chapter 2 Polynomials?

‘Polynomials’ is one of the most important chapters in the Maths syllabus of class 9. The basic highlights of this chapter are listed below.

Polynomial is an algebraic expression consisting of variables, preceded by coefficients, and connected by arithmetic operators. In this chapter, you will learn about polynomials in one variable, that is, the variable coefficient for all the terms in a polynomial, here, will be the same.

The variables along with their coefficients in the algebraic expression are called terms of the polynomial. Some variable terms in a polynomial are raised to exponents.

The degree of a polynomial refers to the greatest exponent of its variable term. If there is a constant term in the polynomial, then it has to be assumed that the exponential value for its variable coefficient is zero.

6. What are the Important Topics Discussed in Class 9 Maths Chapter 2 Polynomials?

Remainder theorem, degree of polynomials, factorization, zeros of a polynomial, algebraic identities, etc., are explained in this chapter. These concepts form the basis of higher mathematics so you must have a good knowledge of these concepts. For example, factorization is one of the most basic concepts of algebra, and you will find its application in other chapters as well.

You may expect sums for finding the degree of polynomials to carry fewer marks in the examination, and mostly these sums are in the compulsory part of the question paper. The sums of the NCERT maths book of class 9 are solved in a step-by-step manner on Vedantu and you may refer to it for a better understanding of all concepts of ‘Polynomials’.

7. How do I identify the degree of a polynomial?

The degree of polynomials in one variable is the highest power of the variable in the algebraic expression.

For example, X^2+5X+3. The degree of this equation is 2.

8. Are NCERT Solutions for Class 9 Maths Chapter 2 difficult to learn?

No, it is easy to score high in your exams if you regularly practice with Vedantu’s NCERT solutions for Class 9 Maths Chapter 2. The solutions are formulated by experienced subject matter experts who understand the CBSE curriculum. The solutions teach you how to present your answers in exams. Every minute detail is covered in a simple way for students to grasp the concepts easily. The solutions are updated according to the latest guidelines of the CBSE board.

9. What is a Polynomial?

Polynomials are expressions that contain one or more terms with coefficients that are not zero. Polynomial terms can be variables, constants, or both. A polynomial's exponents should always be whole numbers. The degree of a polynomial is the highest power in the polynomial. Polynomials are another way to represent real numbers. Further information may be found in Vedantu's NCERT answers for Class 9 Mathematics Chapter 2.

10. What is the Remainder Theorem?

When a polynomial p(x) is divided by the linear polynomial (x-a), then the remainder comes out to be p(a). The degree of the polynomial should be greater than one. For more details, refer to Vedantu’s NCERT solutions for Class 9 Maths Chapter 2. The solution PDFs and other study materials such as important questions and revision notes can also be downloaded from the Vedantu app as well for free of cost. 

11. What are the conditions for an expression to be Polynomial?

The following conditions are important to consider an expression as a polynomial:

All the coefficients should be real numbers.

The exponent should not be a negative number.

What’s New for C++ Developers in Visual Studio 2022 17.10

' data-src=

May 22nd, 2024 7 3

We are happy to announce that Visual Studio 2022 version 17.10 is now generally available! This post summarizes the new features you can find in this release for C++. You can download Visual Studio 2022 from the Visual Studio downloads page  or upgrade your existing installation by following the  Update Visual Studio Learn page .

Standard Library and Compiler

We have incremented the minor version number of the MSVC toolset from 19.39 (VS 2022 v17.9) to 19.40 (VS 2022 v17.10). For more details, and some ways in which this will affect projects that assume that MSVC versions are all 19.3X for Visual Studio 2022 releases, see the  MSVC Toolset Minor Version Number 14.40 in VS 2022 v17.10 blog post .

We’ve made a host of changes to our standard library implementation, with the help of the community. As always, you can see the STL Changelog for full details. We implemented C++26’s P2510R3 Formatting Pointers , which brings the set of format specifiers for pointers when using std::format more in line with those that already exist for integers. We also implemented a few smaller features from C++26 and C++23, such as P2836R1 , which makes std::basic_const_iterator act in a more natural way with respect to implicit conversions. On the performance side, we improved the vectorized implementations of std::min_element , std::ranges::min and friends, made the copy/move assignment operators of std::expected trivial when expected, and more.

C++ Productivity and Game Development

You can now use Build Insights to view your template instantiation information. Template instantiation collection must be activated in Tools > Options > Build Insights.

Recursive Template Instantiation

Check out our blog post on Templates View or our recording from Pure Virtual C++ for more details:

You can now keep our Unreal Engine plugin needed for Unreal Engine Test Adapter running in the background, greatly reducing startup costs. This is an opt-in feature that can be activated via Tools > Options > Unreal Engine. Furthermore, we have added additional Unreal Engine Macros to be indented in accordance with the UE Code Style.

Cross-Platform

If you’re targeting Linux, be sure to check out our video on our most recent development features for Linux from Pure Virtual C++:

CMake Targets View

We have added support for pinning CMake targets in the CMake Targets View. There is a top-level folder now for Pinned Targets. You can pin any targets by right-clicking and selecting the Pin option in the context menu.

Pinning a CMake Target via the context menu

You can also unpin any target in the Pinned Targets folder by selecting Unpin.

Connection Manager

We introduced some UX updates and usability improvements to the Connection Manager. With these updates we provide a more seamless experience when connecting to remote systems and/or debugging failed connections. Check out our blog post for more details.

Screenshot of the updated Connect to Remote System dialog with a failed connection error. The error is displayed above the fields in an info bar and the Host Name and Port field are highlighted and labelled as "may be incorrect". The Connect button is enabled.

Core Editor

View and address pull request comments.

You can now view your GitHub and Azure DevOps pull request comments directly in your working file in Visual Studio. Enable the feature flag, “Pull Request Comments,” in Options > Environment > Preview Features and checkout the pull request branch to get started.

A screen shot of a computer Description automatically generated

Generated Pull Request Descriptions

Similar to our generated  Git commit message feature , you can now get a first draft for your pull request description created by GitHub Copilot. You’ll need to verify you have an active GitHub Copilot subscription. Try it out by clicking the ‘Add AI Generated Pull Request Description’ sparkle pen icon within the Create a Pull Request window. Please share your feedback on this feature  here .

Image Hover Preview

If you hover over the path to an image, Visual Studio will now give you a small preview of the image itself, along with the size of the image in pixels and bytes. The size is capped to 500px wide and high.

A screenshot of a computer Description automatically generated

New Text Formatting Options

You can now choose italic, bold, strikethrough, or underline styles for text formatting in the Options > Environment > Fonts and Colors settings:

Creating Conditional Breakpoints and Tracepoints from Expressions

You can now create a conditional breakpoint or tracepoint directly from an expression in your source code from the right-click menu. This works on property or field names and values from autos, locals, watch windows, or DataTips:

std 9 maths assignment solutions 2022

Attach to Process Dialog Revamp

The Attach to Process dialog has been improved for better functionality and user-friendliness. You can now easily switch between tree and list views, organize processes better with collapsible sections, and select code types with a simplified combobox. Moreover, the “Select/Track Window” feature is now easier to use, allowing two-way tracking: selecting a process highlights its window, and clicking on a window selects its process.

GitHub Copilot

We have unified the experience from the GitHub Copilot and Copilot Chat extensions and shipped them directly in Visual Studio. To install it, install the GitHub Copilot component in the Visual Studio Installer:

Screenshot of the Visual Studio Installer. The GitHub Copilot component is highlighted with an orange outline.

To use it, you’ll need an active GitHub Copilot subscription, and you can find the interface in the top-right corner of Visual Studio.

Very much appreciate the investments you’ve made in the native code tool chain in this release. I’d really like to see more of the same, particularly in the fields of: Code Analysis, scaling the solution for very large projects, local ML based navigational help for large code bases.

With the new version of the MSVC toolset, please consider documenting the behavior of the default value, and add a “latest” value to the corresponding project configuration: https://developercommunity.visualstudio.com/t/Default-value-of-MSVC-Toolset-is-not-doc/10398953

Hi Sy, i see that have been added an image hover preview, could you bring attention from the extension team about this feature request? Its been on “roadmap” for incontable years, almost 100 upvotes and a lot of comments requesting it 🙏🙏 Image Watch

I see there has been some work done on the debugger, but it would be nice if you could let your colleagues on the debugger team know that it is impossible to debug x86 C++ code in Visual Studio 2022 on Intel Sapphire Rapids Xeon CPUs in Windows 11 since August 2023 when those CPUs were released. I submitted a bug report , but it’s “under consideration” seemingly forever. Apparently nobody except me uses workstation class CPUs with Intel AMX instruction set extensions.

' data-src=

too long to wait for std::runtime_format. please update!

' data-src=

Honestly, it’s quite worrying that your FE team was fired. Have you had any luck hiring them back as 50% of your compiler doesn’t exist (and the other 50% from the BE generates worse code compared to competitors from a decade ago)

The lack of C++23 “language” features will soon be a blocker for my industry in particular. We have a set of “reference” guidance and the decision on whether we’re allowed to use C++23 will be made in what looks like a faster timeline then you’ll be able to put the compiler back together again…

Exciting update! But I think the build tools version increase unfortunately broke CUDA with CMake. I’ve submitted https://developercommunity.visualstudio.com/t/VS-2022-1710-C-build-tools-144019/10668943 .

Access Answers to NCERT Class 9 Maths Chapter 1 – Number Systems

Exercise 1.1 page: 5.

1. Is zero a rational number? Can you write it in the form p/q where p and q are integers and q ≠ 0?

We know that a number is said to be rational if it can be written in the form p/q , where p and q are integers and q ≠ 0.

Taking the case of ‘0’,

Zero can be written in the form 0/1, 0/2, 0/3 … as well as , 0/1, 0/2, 0/3 ..

Since it satisfies the necessary condition, we can conclude that 0 can be written in the p/q form, where q can either be positive or negative number.

Hence, 0 is a rational number.

2. Find six rational numbers between 3 and 4.

There are infinite rational numbers between 3 and 4.

As we have to find 6 rational numbers between 3 and 4, we will multiply both the numbers, 3 and 4, with 6+1 = 7 (or any number greater than 6)

i.e., 3 × (7/7) = 21/7

and, 4 × (7/7) = 28/7. The numbers in between 21/7 and 28/7 will be rational and will fall between 3 and 4.

Hence, 22/7, 23/7, 24/7, 25/7, 26/7, 27/7 are the 6 rational numbers between 3 and 4.

3. Find five rational numbers between 3/5 and 4/5.

There are infinite rational numbers between 3/5 and 4/5.

To find out 5 rational numbers between 3/5 and 4/5, we will multiply both the numbers 3/5 and 4/5

with 5+1=6 (or any number greater than 5)

i.e., (3/5) × (6/6) = 18/30

and, (4/5) × (6/6) = 24/30

The numbers in between18/30 and 24/30 will be rational and will fall between 3/5 and 4/5.

Hence,19/30, 20/30, 21/30, 22/30, 23/30 are the 5 rational numbers between 3/5 and 4/5

4. State whether the following statements are true or false. Give reasons for your answers.

(i) Every natural number is a whole number.

Natural numbers- Numbers starting from 1 to infinity (without fractions or decimals)

i.e., Natural numbers = 1,2,3,4…

Whole numbers – Numbers starting from 0 to infinity (without fractions or decimals)

i.e., Whole numbers = 0,1,2,3…

Or, we can say that whole numbers have all the elements of natural numbers and zero.

Every natural number is a whole number; however, every whole number is not a natural number.

(ii) Every integer is a whole number.

Integers- Integers are set of numbers that contain positive, negative and 0; excluding fractional and decimal numbers.

i.e., integers= {…-4,-3,-2,-1,0,1,2,3,4…}

Whole numbers- Numbers starting from 0 to infinity (without fractions or decimals)

i.e., Whole numbers= 0,1,2,3….

Hence, we can say that integers include whole numbers as well as negative numbers.

Every whole number is an integer; however, every integer is not a whole number.

(iii) Every rational number is a whole number.

Rational numbers- All numbers in the form p/q, where p and q are integers and q≠0.

i.e., Rational numbers = 0, 19/30 , 2, 9/-3, -12/7…

All whole numbers are rational, however, all rational numbers are not whole numbers.

Exercise 1.2 Page: 8

1. State whether the following statements are true or false. Justify your answers.

(i) Every irrational number is a real number.

Irrational Numbers – A number is said to be irrational, if it cannot be written in the p/q, where p and q are integers and q ≠ 0.

i.e., Irrational numbers = π, e, √3, 5+√2, 6.23146…. , 0.101001001000….

Real numbers – The collection of both rational and irrational numbers are known as real numbers.

i.e., Real numbers = √2, √5, , 0.102…

Every irrational number is a real number, however, every real number is not an irrational number.

(ii) Every point on the number line is of the form √m where m is a natural number.

The statement is false since as per the rule, a negative number cannot be expressed as square roots.

E.g., √9 =3 is a natural number.

But √2 = 1.414 is not a natural number.

Similarly, we know that there are negative numbers on the number line, but when we take the root of a negative number it becomes a complex number and not a natural number.

E.g., √-7 = 7i, where i = √-1

The statement that every point on the number line is of the form √m, where m is a natural number is false.

(iii) Every real number is an irrational number.

The statement is false. Real numbers include both irrational and rational numbers. Therefore, every real number cannot be an irrational number.

Every irrational number is a real number, however, every real number is not irrational.

2. Are the square roots of all positive integers irrational? If not, give an example of the square root of a number that is a rational number.

No, the square roots of all positive integers are not irrational.

For example,

√4 = 2 is rational.

√9 = 3 is rational.

Hence, the square roots of positive integers 4 and 9 are not irrational. ( 2 and 3, respectively).

3. Show how √5 can be represented on the number line.

Step 1: Let line AB be of 2 unit on a number line.

Step 2: At B, draw a perpendicular line BC of length 1 unit.

Step 3: Join CA

Step 4: Now, ABC is a right angled triangle. Applying Pythagoras theorem,

AB 2 +BC 2 = CA 2

2 2 +1 2 = CA 2 = 5

⇒ CA = √5 . Thus, CA is a line of length √5 unit.

Step 4: Taking CA as a radius and A as a center draw an arc touching

the number line. The point at which number line get intersected by

arc is at √5 distance from 0 because it is a radius of the circle

whose center was A.

Thus, √5 is represented on the number line as shown in the figure.

Ncert solution class 9 chapter 1-1

4. Classroom activity (Constructing the ‘square root spiral’) : Take a large sheet of paper and construct the ‘square root spiral’ in the following fashion. Start with a point O and draw a line segment OP1 of unit length. Draw a line segment P1P2 perpendicular to OP 1 of unit length (see Fig. 1.9). Now draw a line segment P 2 P 3 perpendicular to OP 2 . Then draw a line segment P 3 P 4 perpendicular to OP 3 . Continuing in Fig. 1.9 :

Ncert solution class 9 chapter 1-2

Constructing this manner, you can get the line segment P n-1 Pn by square root spiral drawing a line segment of unit length perpendicular to OP n-1 . In this manner, you will have created the points P 2 , P 3 ,….,Pn,… ., and joined them to create a beautiful spiral depicting √2, √3, √4, …

Ncert solution class 9 chapter 1-3

Step 1: Mark a point O on the paper. Here, O will be the center of the square root spiral.

Step 2: From O, draw a straight line, OA, of 1cm horizontally.

Step 3: From A, draw a perpendicular line, AB, of 1 cm.

Step 4: Join OB. Here, OB will be of √2

Step 5: Now, from B, draw a perpendicular line of 1 cm and mark the end point C.

Step 6: Join OC. Here, OC will be of √3

Step 7: Repeat the steps to draw √4, √5, √6….

Exercise 1.3 Page: 14

1. Write the following in decimal form and say what kind of decimal expansion each has :

NCERT Solution For Class 9 Maths Ex-1.3-1

= 0.36 (Terminating)

NCERT Solution For Class 9 Maths Ex-1.3-2

= 4.125 (Terminating)

NCERT Solution For Class 9 Maths Ex-1.3-4

(vi) 329/400

NCERT Solution For Class 9 Maths Ex-1.3-6

= 0.8225 (Terminating)

2. You know that 1/7 = 0.142857. Can you predict what the decimal expansions of 2/7, 3/7, 4/7, 5/7, 6/7 are, without actually doing the long division? If so, how?

[Hint: Study the remainders while finding the value of 1/7 carefully.]

Ncert solution class 9 chapter 1-9

3. Express the following in the form p/q, where p and q are integers and q 0.

Ncert solution class 9 chapter 1-10

Assume that   x  = 0.666…

Then,10 x  = 6.666…

10 x  = 6 +  x

(ii) \(\begin{array}{l}0.4\overline{7}\end{array} \)

= (4/10)+(0.777/10)

Assume that  x  = 0.777…

Then, 10 x  = 7.777…

10 x  = 7 +  x

(4/10)+(0.777../10) = (4/10)+(7/90) ( x = 7/9 and x = 0.777…0.777…/10 = 7/(9×10) = 7/90 )

= (36/90)+(7/90) = 43/90

Ncert solution class 9 chapter 1-14

Assume that   x  = 0.001001…

Then, 1000 x  = 1.001001…

1000 x  = 1 +  x

4. Express 0.99999…. in the form p/q . Are you surprised by your answer? With your teacher and classmates discuss why the answer makes sense.

Assume that x  = 0.9999…..Eq (a)

Multiplying both sides by 10,

10 x  = 9.9999…. Eq. (b)

Eq.(b) – Eq.(a), we get

10 x  = 9.9999

– x  = -0.9999…

_____________

The difference between 1 and 0.999999 is 0.000001 which is negligible.

Hence, we can conclude that, 0.999 is too much near 1, therefore, 1 as the answer can be justified.

5. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17 ? Perform the division to check your answer.

Dividing 1 by 17:

NCERT Solution For Class 9 Maths Ex-1.3-7

There are 16 digits in the repeating block of the decimal expansion of 1/17.

6. Look at several examples of rational numbers in the form p/q (q ≠ 0), where p and q are integers with no common factors other than 1 and having terminating decimal representations (expansions). Can you guess what property q must satisfy?

We observe that when q is 2, 4, 5, 8, 10… Then the decimal expansion is terminating. For example:

1/2 = 0. 5, denominator q = 2 1

7/8 = 0. 875, denominator q =2 3

4/5 = 0. 8, denominator q = 5 1

We can observe that the terminating decimal may be obtained in the situation where prime factorization of the denominator of the given fractions has the power of only 2 or only 5 or both.

7. Write three numbers whose decimal expansions are non-terminating non-recurring.

We know that all irrational numbers are non-terminating non-recurring. three numbers with decimal expansions that are non-terminating non-recurring are:

  • √3 = 1.732050807568
  • √26 =5.099019513592
  • √101 = 10.04987562112

8. Find three different irrational numbers between the rational numbers 5/7 and 9/11.

Ncert solution class 9 chapter 1-17

Three different irrational numbers are:

  • 0.73073007300073000073…
  • 0.75075007300075000075…
  • 0.76076007600076000076…

9.  Classify the following numbers as rational or irrational according to their type:

√23 = 4.79583152331…

Since the number is non-terminating and non-recurring therefore, it is an irrational number.

√225 = 15 = 15/1

Since the number can be represented in p/q form, it is a rational number.

(iii) 0.3796

Since the number,0.3796, is terminating, it is a rational number.

(iv) 7.478478

The number,7.478478, is non-terminating but recurring, it is a rational number.

(v) 1.101001000100001…

Since the number,1.101001000100001…, is non-terminating non-repeating (non-recurring), it is an irrational number.

Exercise 1.4 Page: 18

1. Visualise 3.765 on the number line, using successive magnification.

Ncert solutions class 9 chapter 1-18

Exercise 1.5 Page: 24

1. Classify the following numbers as rational or irrational:

We know that, √5 = 2.2360679…

Here, 2.2360679…is non-terminating and non-recurring.

Now, substituting the value of √5 in 2 –√5, we get,

2-√5 = 2-2.2360679… = -0.2360679

Since the number, – 0.2360679…, is non-terminating non-recurring, 2 –√5 is an irrational number.

(ii) (3 +√23)- √23

(3 + √ 23) –√23 = 3+ √ 23–√23

Since the number 3/1 is in p/q form, ( 3 +√23)- √23 is rational.

(iii) 2√7/7√7

2√7/7√7 = ( 2/7)× (√7/√7)

We know that (√7/√7) = 1

Hence, ( 2/7)× (√7/√7) = (2/7)×1 = 2/7

Since the number, 2/7 is in p/q form, 2√7/7√7 is rational.

Multiplying and dividing numerator and denominator by √2 we get,

(1/√2) ×(√2/√2)= √2/2 ( since √2×√2 = 2)

We know that, √2 = 1.4142…

Then, √2/2 = 1.4142/2 = 0.7071..

Since the number , 0.7071..is non-terminating non-recurring, 1/√2 is an irrational number.

We know that, the value of = 3.1415

Hence, 2 = 2×3.1415.. = 6.2830…

Since the number, 6.2830…, is non-terminating non-recurring, 2 is an irrational number.

2. Simplify each of the following expressions:

(i) (3+√3)(2+√2)

(3+√3)(2+√2 )

Opening the brackets, we get, (3×2)+(3×√2)+(√3×2)+(√3×√2)

= 6+3√2+2√3+√6

(ii) (3+√3)(3-√3 )

(3+√3)(3-√3 ) = 3 2 -(√3) 2 = 9-3

(iii) (√5+√2) 2

(√5+√2) 2 = √5 2 +(2×√5×√2)+ √2 2

= 5+2×√10+2 = 7+2√10

(iv) (√5-√2)(√5+√2)

(√5-√2)(√5+√2) = (√5 2 -√2 2 ) = 5-2 = 3

3. Recall, π is defined as the ratio of the circumference (say c) of a circle to its diameter, (say d). That is, π =c/d. This seems to contradict the fact that π is irrational. How will you resolve this contradiction?

There is no contradiction. When we measure a value with a scale, we only obtain an approximate value. We never obtain an exact value. Therefore, we may not realize whether c or d is irrational. The value of π is almost equal to 22/7 or 3.142857…

4. Represent (√9.3) on the number line.

Step 1: Draw a 9.3 units long line segment, AB. Extend AB to C such that BC=1 unit.

Step 2: Now, AC = 10.3 units. Let the centre of AC be O.

Step 3: Draw a semi-circle of radius OC with centre O.

Step 4: Draw a BD perpendicular to AC at point B intersecting the semicircle at D. Join OD.

Step 5: OBD, obtained, is a right angled triangle.

Here, OD 10.3/2 (radius of semi-circle), OC = 10.3/2 , BC = 1

OB = OC – BC

⟹ (10.3/2)-1 = 8.3/2

Using Pythagoras theorem,

OD 2 =BD 2 +OB 2

⟹ (10.3/2) 2 = BD 2 +(8.3/2) 2

⟹ BD 2 = (10.3/2) 2 -(8.3/2) 2

⟹ (BD) 2 = (10.3/2)-(8.3/2)(10.3/2)+(8.3/2)

⟹ BD 2  = 9.3

⟹ BD =  √9.3

Thus, the length of BD is √9.3.

Step 6: Taking BD as radius and B as centre draw an arc which touches the line segment. The point where it touches the line segment is at a distance of √9.3 from O as shown in the figure.

5. Rationalize the denominators of the following:

Multiply and divide 1/√7 by √7

(1×√7)/(√7×√7) = √7/7

(ii) 1/(√7-√6)

Multiply and divide 1/(√7-√6) by (√7+√6)

= (√7+√6)/√7 2 -√6 2 [denominator is obtained by the property, (a+b)(a-b) = a 2 -b 2 ]

= (√7+√6)/(7-6)

= (√7+√6)/1

(iii) 1/(√5+√2)

Multiply and divide 1/(√5+√2) by (√5-√2)

= (√5-√2)/(√5 2 -√2 2 ) [denominator is obtained by the property, (a+b)(a-b) = a 2 -b 2 ]

= (√5-√2)/(5-2)

= (√5-√2)/3

(iv) 1/(√7-2)

Multiply and divide 1/(√7-2) by (√7+2)

1/(√7-2)×(√7+2)/(√7+2) = (√7+2)/(√7-2)(√7+2)

= (√7+2)/(√7 2 -2 2 ) [denominator is obtained by the property, (a+b)(a-b) = a 2 -b 2 ]

= (√7+2)/(7-4)

Exercise 1.6 Page: 26

64 1/2 = (8×8) 1/2

= 8 1 [⸪2×1/2 = 2/2 =1]

32 1/5 = (2 5 ) 1/5

= 2 1 [⸪5×1/5 = 1]

(iii)125 1/3

(125) 1/3 = (5×5×5) 1/3

= 5 1 (3×1/3 = 3/3 = 1)

9 3/2 = (3×3) 3/2

= (3 2 ) 3/2

= 3 3 [⸪2×3/2 = 3]

(ii) 32 2/5

32 2/5 = (2×2×2×2×2) 2/5

= (2 5 ) 2⁄5

= 2 2 [⸪5×2/5= 2]

(iii)16 3/4

16 3/4 = (2×2×2×2) 3/4

= (2 4 ) 3⁄4

= 2 3 [⸪4×3/4 = 3]

(iv) 125 -1/3

125 -1/3 = (5×5×5) -1/3

= (5 3 ) -1⁄3

= 5 -1 [⸪3×-1/3 = -1]

3. Simplify :

(i) 2 2/3 ×2 1/5

2 2/3 ×2 1/5 = 2 (2/3)+(1/5) [⸪Since, a m ×a n =a m+n ____ Laws of exponents]

= 2 13/15 [⸪2/3 + 1/5 = (2×5+3×1)/(3×5) = 13/15]

(ii) (1/3 3 ) 7

(1/3 3 ) 7 = (3 -3 ) 7 [⸪Since,(a m ) n = a m x n ____ Laws of exponents]

(iii) 11 1/2 /11 1/4

11 1/2 /11 1/4 = 11 (1/2)-(1/4)

= 11 1/4 [⸪(1/2) – (1/4) = (1×4-2×1)/(2×4) = 4-2)/8 = 2/8 = ¼ ]

(iv) 7 1/2 ×8 1/2

7 1/2 ×8 1/2 = (7×8) 1/2 [⸪Since, (a m ×b m = (a×b) m ____ Laws of exponents]
