a^n is negative when... a is negative, and n is an odd number or when n is between 1 and 0
a^n is positive when a is positive, n can be anything

The way to figure this out (which is what I know you really meant to ask) is to pick any number, positive or negative, and call it "a". Now multiply it by itself "n" times. Pick any number for "n". Keep the numbers small, like 1, 2, 3, etc. See when the result comes out positive and when it comes out negative. See if there's a pattern.

a^n is negative when a is negative & n is odd.
Ex. (-1)^3 = (-1)(-1)(-1) = -1.
[If n is odd, n - 1 is even. The product of two factors with differing signs is negative.]
a^n is positive, either when a is positive or negative & n is even or a is positive & n is even or odd.
Ex. (2)^2 = 4
Ex. (-2)^2 = 4
Ex. (3)^2 = 9
EX.(3)^1 = 3

a^n is positive when a is positive. cuz +^anything is positive (+x+=+).
a^n is negative when n is odd and a is negative. when a - shows up an even number of times, it cancels to a plus, so n must be odd for the answer to be negative.
