Q.

8

Without using a calculator, find an irrational number between

\newline

(a)

4

and

5

.

\newline

9

Without using a calculator, estimate

Find Square Root: We know that the square root of $16$ is $4$ and the square root of $25$ is $5$ . So we need to find a number between $16$ and $25$ whose square root is irrational.
Identify Number Between: The number $17$ is between $16$ and $25$ , and its square root cannot be expressed as a fraction, making it an irrational number.
Determine Irrationality: So, the square root of $17$ , which is written as $\sqrt{17}$ , is an irrational number between $4$ and $5$ .
