(3)^(-2) = (1)/(3^2) = 1/9
8
You simply do all the calculations. Remember that powers must be calculated before multiplications (unless there is a more complicated expression in the exponent, in which case this expression must be evaluated first).
To solve 8 to power 25, you either need the mathematical tables or a scientific calculator.
8 1/3 = ab^-1, 1.8 =ab^2
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
8
it's the same as 1 over the same number to a positive power. 2 to the power -3 = 1/ 2 cubed = 1/8
2 to the power of minus 3 is equivalent to 1/8. To calculate this, we can use the following formula: 2−3=231=81 Therefore, 2 to the power of minus 3 is equal to 1/8.

PLUS 2
(-10) to the power of negetive 2
8 1/3 = ab^-1, 1.8 =ab^2
The equation to solve is given by. |-2 x + 2| -3 = -3 Add 3 to both sides of the equation and simplify. |-2 x + 2| = 0 |-2 x + 2| is equal to 0 if -2 x + 2 = 0. Solve for x to obtain. So, x = 1
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
Solve for n. 2n+3=0 2n=-3 n=-3/2
Factor it. y(4y - 1)(3y - 2) = 0 y = 0, 1/4, 2/3
