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

- \frac{6 ( 9 x + 1 )}{( ( 9 x + 1 ) ^{2} ) ^{\frac{4}{3}}}

Schritte zur Lösung

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

Wende Exponentenregel an:

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

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

Wende die Kettenregel an:

- \frac{1}{3 ( ( 9 x + 1 ) ^{2} ) ^{\frac{4}{3}}} \frac{d}{d x} ((9 x + 1)^{2})

= - \frac{1}{3 ( ( 9 x + 1 ) ^{2} ) ^{\frac{4}{3}}} \frac{d}{d x} ((9 x + 1)^{2})

\frac{d}{d x} ((9 x + 1)^{2}) = 18 (9 x + 1)

= - \frac{1}{3 ( ( 9 x + 1 ) ^{2} ) ^{\frac{4}{3}}} \cdot 18 (9 x + 1)

Vereinfache

= - \frac{6 ( 9 x + 1 )}{( ( 9 x + 1 ) ^{2} ) ^{\frac{4}{3}}}
