$- 5 x^{- \frac{1}{3}}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$- 5 \frac{1}{x^{\frac{1}{3}}}$

Step 2

Apply the rule $x^{\frac{m}{n}} = \sqrt[n]{x^{m}}$ to rewrite the exponentiation as a radical.

$- 5 \frac{1}{\sqrt[3]{x^{1}}}$

Step 3

Anything raised to $1$ is the base itself.

$- 5 \frac{1}{\sqrt[3]{x}}$
