These free downloadable pdfs of class 8 Class 9 Maths Chapter 3 Question Answer And maths extra questions cover all the additional questions from the entire syllabus chapter-wise, along with solutions.
Question 1 - this set of questions are called Very short answer type of Questions. The questions here are of one mark each. The problems in this section will look simple but tend to be very tricky at times.
The answers expected here will take only one or two steps to get the solution provided you have a proper conceptual understanding of the question asked. The various types of very short answer type questions that would be asked are. Fill in the blanks - Here you are expected to complete the sentences to make them meaningful. These sentences tend to be usually part of various theories of mathematical statements which you need to complete.
State whether the following are True or False - In this section, statements or expressions are given and you have to solve them or analyze them and state whether they are true or false. Choose the correct option - This section tend to come very rarely in Maths paper, but it is always safe to be aware of them. But only one of the four options is the correct answer.
You are supposed to figure out the correct answer. Getting a result 2. Equally likely outcomes 3. Linking chances to probability Question Answer Maths Class 9 Vectors 4. Outcomes as events 5. Chance and probability related to real life Keypoints are listed in the end. In this chapter, students will learn to find squares and square roots of any number. The chapter will be fun to study as students will get to experiment more with the numbers.
In general, if a natural number m can be expressed as n 2 , where n is also a natural number, then m is a square number. Properties of square numbers will be explained in this chapter. Some more interesting patterns are also discussed. Section 6. The section is subdivided into the following points: 1. Other patterns in squares 2.

Perfect cubes or cube numbers are explained. This section is further divided into sub-parts. One will come across interesting patterns related to cubes. Not only this cubes and their prime factors will be taught followed by smallest multiple which is a perfect cube.
Exercise 7. Moving further students will learn about cube roots in the next section. This includes methods like prime factorisation and estimation method. The last exercise is 7. The chapter ends with a summary. Solved examples are given in the chapter for a better explanation. The next section is about Finding the Increase or Decrease Percent. After that, Finding discounts will be explained. Moving on to the next section, section 8.

Terms like monomials, binomials, trinomials and polynomials are discussed in detail. Emphasis is given to important topics like Addition and subtraction of algebraic expressions. Like and unlike terms are discussed under section 9. The discussion moves further to the next topic- multiplication of algebraic expressions.
This topic contains various subparts. All subparts are explained in great detail. Ever wondered what is an identity? This chapter will clear all doubts of students relating to the same concept- Identity. That will help you in solving all the questions in the stipulated time frame during the final exam.
