9^2
3 squared=9. it =9 because when a number is squared it means to multiply by itself. ex-3 squared 3x3=9. that's all it is
Yes, it is.
The next number in the series 2-4-3-9-4 is 16. 2 squared is 4, 3 squared is 9, 4 squared is 16
Any number that can be written as a fraction is rational -- therefore, 4/9 squared is rational (it can still be written as a fraction even if you multiply it by itself).
9 Squared is 81.Squared means to times a number by itself so..... 9 squared = 9x9 = 81!
9 + 16 = 25
-9 or +9.
yes it isThe square root of 81 is 9.
