Rewrite the base with a positive exponent in the denominator: (a^{-n} = frac{1}{a^n})
Move a factor with a negative exponent from numerator to denominator, or from denominator to numerator
Keep the base the same and make the exponent positive
Apply the rule to each factor separately
For a fraction with a negative exponent, invert the fraction and change the exponent to positive
For a product with a negative exponent, distribute the exponent before rewriting
Use (a^0 = 1) when needed to simplify expressions
Remember (a^{-1} = frac{1}{a})
Remember (left(frac{a}{b}right)^{-n} = left(frac{b}{a}right)^n)
Simplify the result after rewriting with positive exponents
