derivative of

f (x) = \frac{4}{x ^{5}}

- \frac{20}{x ^{6}}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the Power Rule:

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

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

Simplify

4 (- 5 x^{- 5 - 1}) : - \frac{20}{x ^{6}}

= - \frac{20}{x ^{6}}
