Standardizing Engineering Formulas: Cube Roots

A civil engineering intern is standardizing a formula for the load-bearing capacity of a structural beam. The formula results in an expression with the term 1k3\frac{1}{\sqrt[3]{k}} in the denominator. To rationalize this denominator according to technical documentation standards, what radical expression must the intern multiply both the numerator and the denominator by?
