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).
8 1/3 = ab^-1, 1.8 =ab^2
To solve 8 to power 25, you either need the mathematical tables or a scientific calculator.
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2

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
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
Solve for n. 2n+3=0 2n=-3 n=-3/2
To solve -5+2+(-3), start by adding -5 and 2 together which equals -3. Then, add -3 to -3 which gives you a final answer of -6.

3^(-4) = (1/3)^4 = 1/81
The LCM of 17, 27, and 54 is 54. To solve, write each of the numbers in their prime factorization in power form and then multiply together the value of the highest power of all the primes across all the numbers. 18 = 2 x 3^2 27 = 3^3 54 = 2 x 3^3 Highest power of each prime is: 2 and 3^3, so the LCM = 2 x 3^3 = 54.
For anything to the power of a negative, put the number as the denominator in 1/? and then solve (ex: 2 to the power of neg. 2 = 1/2 to the power of 2 = 1/4)
