Because 9*9 = 81 which is a square number or a perfect square.

16(2)-36+9 32-36+9 -4+9 No, it isn't a perfect square.

Because 9 is a perfect square - which means that its square root is an integer. 3 is not a perfect square.

The square root of a non-perfect square may be irrational and therefore may not be easy to find. However, it need not be.For example, 2.25 is not a perfect square but 2.25 = 9/4 and both 9 and 4 are perfect squares. So sqrt(2.25) = sqrt(9/4) = sqrt(9)/sqrt(4) = 3/2 = 1.5. Not that difficult!

Yes, nine is a perfect squarebecause 9 = 3*3
