Question

Which two consecutive whole

Answer 1

Given:

The value is $\sqrt{90}$.

To find:

The two consecutive whole numbers such that $\sqrt{90}$ lies between those numbers.

Solution:

The perfect square numbers between 1 to 100 are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.

We know that, 90 lies between 81 and 100.

$81$

$9^2$

The value of x radical cannot be negative. So taking square root on each side, we get

$\sqrt{9^2}$

$9$

The given number lies between 9 and 10. Therefore, the correct option is (d)
