$\dfrac{1}{x^3}$

#### Work Step by Step

Using the laws of exponents, the given expression, $(x^{3})^{-1} ,$ is equivalent to \begin{array}{l}\require{cancel} x^{3(-1)} \\\\= x^{-3} \\\\= \dfrac{1}{x^3} .\end{array} For more complicated problems, it is helpful to remember that you can flip the location of numbers with negative exponents. In other words, you can move numbers with a negative exponent that are in the numerator to the denominator, and you can move numbers with a negative exponent in the denominator to the numerator.
