The perfect square of 9 is 81.
Because 9*9 = 81 which is a square number or a perfect square.
81 is a perfect square because 81 = 9 x 9
8 is a perfect cube; it is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer....you're thinking of 9...
16(2)-36+9 32-36+9 -4+9 No, it isn't a perfect square.
A perfect square is a rational number that is the square of another rational number. 9, 16, 25, etc., are perfect squares of 3, 4, 5, etc., and X2 + 6X + 9 is a perfect square of (X + 3).
81 is a perfect squarebecause 81 = 9*9. It is NOT a perfect cube.
Because 9 is a perfect square - which means that its square root is an integer. 3 is not a perfect square.
9
All numbers have factors. Some factors are perfect squares. We call these perfect square factors. 9 is a perfect square factor of 27.
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
