**7. How can I make a study plan for preparing Chapter 1 of Class 9 Maths?**

**To make a successful study plan for preparing the Chapter 1 Number System given in the Class 9 Maths book, you should follow the given steps:**

Build a schedule balanced with all your daily activities.

Set a timetable and have a designated study area.

Limit your study time to two hours on this chapter to ensure you don’t lose your focus. You can increase or decrease the time limit according to your preference. During this time, read all the important concepts, solve questions, etc.

**8. State whether the statement is true or false. Every point on the number line is in the form of √m where m is a natural number.**

The given statement is false. It is wrong according to the norm ‘ a negative can’t be expressed as square roots.

For example- √16= 4 where 4 is a natural number. On the other hand, √3= 1.73 which is not a natural number. Similarly, negative numbers can also be represented on the number line but we know that a negative number changes into a complex number if we take the root of a negative number. For instance- √-8= 8i where i = √-1. Hence, the statement- every point on the number line is in the form of √m where m is a natural number is wrong.
