16000,2500000,1000,169000,9000,81000 these are not perfect squares.
but how....please explain it with solutions
1 x 16,000 2 x 8,000 4 x 4,000,etc.
There are a lot of factors!
But,we want a factor combination with equal numbers like 3x3,4×4,etc.
So as there Is not a equal factor combination for 16,000 it's not a perfect square.
Similarly,we can prove that other numbers like 169000,81000,etc.are not perfect squares.
