812 = 6561
9 to the power of 2 = 81
11
81. (9 to the power of 2 = 9 x 9).
You can express 81 using different exponents as follows: (81 = 3^4), since (3 \times 3 \times 3 \times 3 = 81). Additionally, (81 = 9^2) because (9 \times 9 = 81) and (9) can also be written as (3^2), giving (81 = (3^2)^2 = 3^4). Lastly, (81 = 81^1) is another representation, where any number to the power of 1 remains unchanged.
± 3 to the fourth power equals 81.
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.)
