derivative of

(9 x + 2)^{\frac{2}{3}}

\frac{6}{( 9 x + 2 ) ^{\frac{1}{3}}}

Solution steps

\frac{d}{d x} ((9 x + 2)^{\frac{2}{3}})

Apply the chain rule:

\frac{2}{3 ( 9 x + 2 ) ^{\frac{1}{3}}} \frac{d}{d x} (9 x + 2)

= \frac{2}{3 ( 9 x + 2 ) ^{\frac{1}{3}}} \frac{d}{d x} (9 x + 2)

\frac{d}{d x} (9 x + 2) = 9

= \frac{2}{3 ( 9 x + 2 ) ^{\frac{1}{3}}} \cdot 9

Simplify

\frac{2}{3 ( 9 x + 2 ) ^{\frac{1}{3}}} \cdot 9 : \frac{6}{( 9 x + 2 ) ^{\frac{1}{3}}}

= \frac{6}{( 9 x + 2 ) ^{\frac{1}{3}}}
