1. When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$$5^{-2}$$ or $$\frac{5^{-2}}{1}=\frac{1}{5^2} =\frac{1}{25}$$

$$\frac{1}{x^{-4}}=\frac{x^4}{1}$$ or  $$x^4$$

$$3x^{-5}$$ or  $$3^1x^{-5}=\frac{3}{x^5}$$

$$9a^{-1}$$    Make the exponent positive

$$\frac{9}{a}$$        (this is as far as you can simplify)
