derivative of

\frac{1}{x ^{\frac{2}{3}}}

- \frac{2}{3 x ^{\frac{5}{3}}}

Solution steps

\frac{d}{d x} (\frac{1}{x ^{\frac{2}{3}}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= \frac{d}{d x} (x^{- \frac{2}{3}})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= - \frac{2}{3} x^{- \frac{2}{3} - 1}

Simplify

- \frac{2}{3} x^{- \frac{2}{3} - 1} : - \frac{2}{3 x ^{\frac{5}{3}}}

= - \frac{2}{3 x ^{\frac{5}{3}}}
