Question

Complete the following:

${18}^2=324$

So, $\sqrt{324}=$ _________.

Answer 1

Find the missing value:

It is given that square of $18$ is $324$.

So, $\sqrt{324}=$$\sqrt{2\times 2\times 3\times 3\times 3\times 3}$

$\Rightarrow \sqrt{324}=2\times 3\times 3$

$\Rightarrow \sqrt{324}=$$18$

Thus, the missing value is $18$.
