Yes. The answer is......................................................................................................................................................................................................................................................2.

9h + 2 = -79 9h = -81 h = -81/9 h = -9

(x2 - 3)(x2 + 3)(x4 + 9)

The square root of 81 is: ±9 (9 or -9)A square root is a number which, when multiplied by itself, equals the original number. As 9 x 9 = 81 and -9 x -9 = 81, the answer is plus or minus nine.

The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2

how do you not know it is of course cos 9 times 9 equals to 81

729/81 = 9

81 x 81 = 6561

How about: 9 times 9 = 81 or 81 times 1 = 81
