Question

Find the square root of $216$.

Answer 1

Compute the square root of the given number.

The given number is $216$.

$\therefore$prime factors of $216$ are:

$216=2\times 2\times 2\times 3\times 3\times 3$

Taking Square root on both sides

$$\begin{gathered} \sqrt{216}=\sqrt{2\times 2\times 2\times 3\times 3\times 3} \\ \Rightarrow \sqrt{216}=6\sqrt{6} \\ \Rightarrow \sqrt{216}=6\left(2.45\right) \\ \Rightarrow \sqrt{216}=14.7 \end{gathered}$$

Hence the square root of $216$ is $14.7$
