Rewrite the expression with rational exponents. \( \sqrt[3]{18} \) \( \sqrt[3]{18}=\square \)

To rewrite the expression \( \sqrt[3]{18} \) with rational exponents, we can use the property that the \( n \)-th root of a number can be expressed as that number raised to the power of \( \frac{1}{n} \). In this case, the cube root can be expressed as: \[ \sqrt[3]{18} = 18^{\frac{1}{3}} \] Thus, we have: \[ \sqrt[3]{18} = 18^{\frac{1}{3}} \] So, the final answer is: \[ \sqrt[3]{18} = 18^{\frac{1}{3}} \]
