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

- \frac{4}{5 x ^{5}}

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply exponent rule:

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

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

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

Simplify

\frac{1}{5} (- 4 x^{- 4 - 1}) : - \frac{4}{5 x ^{5}}

= - \frac{4}{5 x ^{5}}

\frac{d}{d x} (e^{- l n (x)})

\int_{- 1}^{3} (x^{3} + 2 x - 5) d x

x \to 4 lim (x - 5)

\int - 2 x^{4} d x

y = x^{2} - 2 x, y = - x^{2} + 6 x
