Question

how find the values of
$\sqrt{?} numbers$

Answer 1

by finding their prime factorisation



suppose u take
$\sqrt{144}$

then u find the prime factorisation

$\sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3}$
then make pair of two time digits
$2 \times 2 \times 3$
then u have to do simple multiplication and u got the answer
$12$
