A negative exponent is very different from a negative base, which is different from an exponential function multiplied by negative one. A negative exponent changes whether the base will be in the top or bottom of a fraction. A negative base to an odd power will still be negative, whereas a negative base to an even power will be positive. If you have a negative in front of your exponential expression, evaluate the exponent, and then multiply the result by negative one.
