$- {(3 k^{3})}^{- \frac{2}{7}}$

Step 1

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

$- \frac{1}{{(3 k^{3})}^{\frac{2}{7}}}$

Step 2

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

$- \frac{1}{\sqrt[7]{{(3 k^{3})}^{2}}}$
