If you have a number raised to a negative(2^-1), you make it one over the base (1/2) and raise the base to the absolute value of the power(1/(2^1))
I DO realize that that is confusing. I learned it in my ACT study book.

2^-1 = 1/(2^1) = 1/2

Any number raised to the first power is that number. Example: 6 to the first is 6. 2 to the first is 2. The power sign indicates how many times a number is multiplied by itself. 2 squared is 2x2 = 4, but 2 to the one power is just 2.

The answer is 1/2.
Raising a nonzero number to the â1 power produces its reciprocal.

One half or 1/2

this is a formula:
x^(-a) = 1/(x^a)
so 2^(-1) = 1/(2^1) = 1/2
OK?
