\frac{d}{d x} (ln (x^{\frac{1}{5}}))

\frac{1}{5 x}

Solution steps

\frac{d}{d x} (ln (x^{\frac{1}{5}}))

Apply the chain rule:

\frac{1}{x ^{\frac{1}{5}}} \frac{d}{d x} (x^{\frac{1}{5}})

= \frac{1}{x ^{\frac{1}{5}}} \frac{d}{d x} (x^{\frac{1}{5}})

\frac{d}{d x} (x^{\frac{1}{5}}) = \frac{1}{5 x ^{\frac{4}{5}}}

= \frac{1}{x ^{\frac{1}{5}}} \cdot \frac{1}{5 x ^{\frac{4}{5}}}

Simplify

\frac{1}{x ^{\frac{1}{5}}} \cdot \frac{1}{5 x ^{\frac{4}{5}}} : \frac{1}{5 x}

= \frac{1}{5 x}

\int x^{2} + x^{- 2} d x

sin (2 x) d x + cos (6 y) d y = 0

y = 4 x^{2}, y = 6 x^{2}, 5 x + y = 6

(2 x - 3)^{2}
