$\sqrt{4}$= 2 where 2 is a rational number . Here n is perfect square the $\sqrt{n}$ is rational number

$\sqrt{5}$ = 2.236.. is not rational number But it is irrational number.here n is not a perfect square the $\sqrt{n}$ is irrational number

So $\sqrt{n}$ is not irrational number if n is perfect square.
