Is 336 a perfect square ?

assidaveTexziiy

Given number is 336
First we factorise it
$\begin{array}{|cc|}\hline 2& 336\\ 2& 168\\ 2& 84\\ 2& 42\\ 3& 21\\ 7& 7\\ & 1\\ \hline\end{array}$
$336=\underset{_}{2×2}×\underset{_}{2×2}×\underset{_}{3×7}$
Clearly, 3 and 7 do not have a pair, so it is not a perfect square.

Do you have a similar question?
