derivative of

f (x) = (x^{7} + 5 x)^{\frac{1}{3}}

\frac{7 x ^{6} + 5}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}}

Solution steps

\frac{d}{d x} ((x^{7} + 5 x)^{\frac{1}{3}})

Apply the chain rule:

\frac{1}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}} \frac{d}{d x} (x^{7} + 5 x)

= \frac{1}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}} \frac{d}{d x} (x^{7} + 5 x)

\frac{d}{d x} (x^{7} + 5 x) = 7 x^{6} + 5

= \frac{1}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}} (7 x^{6} + 5)

Simplify

\frac{1}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}} (7 x^{6} + 5) : \frac{7 x ^{6} + 5}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}}

= \frac{7 x ^{6} + 5}{3 ( x ^{7} + 5 x ) ^{\frac{2}{3}}}

\int \frac{x}{x ^{2} + 16} d x

e^{3 x} sin (6 x)

\int \frac{x}{x - 21} d x

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

\int_{0}^{1} x^{2} + 1 d x
