Question

Estimate the value of $\sqrt{22}$

Answer 1

Given $\sqrt{22}$

By long division method $\sqrt{22}=4.690$ i.e,

Hence, the value of $\sqrt{22}$ is $4.690$

To estimate the $4.690$

On rounding off the numbers we get

$4.690$ rounds off to $5$

Hence, the estimate the value of $\sqrt{22}$ is $5$.
