Power in denominator

Theory

Power in denominator

If a power is in the denominator of a fraction with the numerator 11 it can be written as a power with a negative exponent. It can be shown by using the Quotient of Powers Property. 135=3035=305=3-5 \dfrac{1}{3^5}=\dfrac{3^0}{3^5}=3^{0-5}=3^{\text{-}5}
