\frac{d}{d x} (3 3 x)

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

Solution steps

\frac{d}{d x} (3 3 x)

Apply the chain rule:

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

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

\frac{d}{d x} (3 x) = 3

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

Simplify

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

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