9 to the power of 2 = 81
11
81. (9 to the power of 2 = 9 x 9).
± 3 to the fourth power equals 81.
9^2 = 81 Which is the same as 9 * 9 = 81 For instance, if it was 9 to the power of 3: it would by 9 * 9 * 9 = 729 (could also be expressed as 9^3) (Note: x . * are three symbols meaning multiply.)
It is: 9^2 = 81
9 to the power of 2 = 81

81 = 34
81. (9 to the power of 2 = 9 x 9).
92 = 81
92=81 2-81= -79
Because 9 times 9 equals 81.
81
2^9 = 512 9^2 = 81
3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1
81 = 9^2 = 3^4 ("^" means "to the power of" - ^2 = squared, ^3 = cubed, etc.)
