Converting to Positive Powers/Exponents

Sometimes, you are asked to make sure all of the exponents in your answer are positive. To convert any exponent from negative to positive you either move the variable from the numerator to the denominator or you move the variable from the denominator to the numerator. You may have heard this rule called the elevator rule, because you can imagine the variable hopping into an elevator and moving up or down one floor.

The rule is:

x^(-n)=1/x^n
or
1/x^(-n)=x^n
