$a^2=a(a)=(-a)(-a)$

A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.  $\sqrt{a}$

On the same concept , square root of 54 will :

⇒ $\sqrt{54}$

⇒ $+7.34846922835 , -7.34846922835$

∴ Exact square root of 54 is $+7.34846922835 , -7.34846922835$ .
