- \frac{7}{3 x ^{\frac{4}{3}}}

Solution steps

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

Apply exponent rule:

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

= 7 \frac{d}{d x} (x^{- \frac{1}{3}})

Apply the Power Rule:

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

= 7 (- \frac{1}{3} x^{- \frac{1}{3} - 1})

Simplify

7 (- \frac{1}{3} x^{- \frac{1}{3} - 1}) : - \frac{7}{3 x ^{\frac{4}{3}}}

= - \frac{7}{3 x ^{\frac{4}{3}}}
