Powers with a negative exponent can be written as a FRACTION with a POSITIVE exponent. Example: a-5 = Conversely, a fraction whose denominator has an exponent can be written as a power with a NEGATIVE exponent. Example: = a-9. Rule #5: A Power with an Exponent of One. When evaluating a power with an exponent of one, the answer will be the base.
