9 squared equals 81.

The square root of 81 squared is 81.

One: 81 squared = 81^2 = 6561

Because: (9-x)(9-x) = 81-18x+x^2

9 x 9 = 81 9 squared = 81 3 squared times 3 squared = 81

92 = 81122 = 14481 + b2 = 144(take 81 from both sides)b2 = 63b = 7.937253933

The answer? There is no "answer" There cannot be an answer because they are all different. In order to make calculations, the variables have to be the same. x squared, xy, y squared are the variables, and none of them match. Therefore your "answer" must look like this: 9x squared - 6xy + y squared - 81. Hope I Helped :D

9 Squared is 81.Squared means to times a number by itself so..... 9 squared = 9x9 = 81!

The area of square with a perimeter of 36 is 81. If the perimeter is 36, then each side must be 36 divided by 4, or 9. The area of a square is side squared, so that is 9 squared or 81.

9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)

90

3x squared - (3x) squared = 0

9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)

-9 squared is 81.

81 9*9=8181

9 squared is 81 and 16 squared is 256

0.1111

812 = 81 x 81 = 6,561

(2x - 9)(2x - 9) or (2x - 9)2

92+18-(12/2*5) 81+18-(6*5) 99-30 69

2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.

4 x4 x4=64 + 13=77- - 4=81+(14x14=196)=277
