**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.
