we have to show that the number is a perfect square or not.
for eg ..b part of your question
1764
we have to factorise it
1764 = 2 * 2* 3 * 3 * 7* 7
here we can clearly see that factors are in pair.
if the factors are in pair then for sure its a perfect square.
Your question has been done !
just for ur knowledge - to find square root
we have to take out one number from each pair and multiply.
like here ,square root of 1764 is 2 * 3 * 7
=42
( 42 * 42 = 1764 0
