\frac{d}{d x} (- \frac{14}{x ^{4}})

\frac{56}{x ^{5}}

Solution steps

\frac{d}{d x} (- \frac{14}{x ^{4}})

Take the constant out:

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

= - 14 \frac{d}{d x} (\frac{1}{x ^{4}})

Apply exponent rule:

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

= - 14 \frac{d}{d x} (x^{- 4})

Apply the Power Rule:

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

= - 14 (- 4 x^{- 4 - 1})

Simplify

- 14 (- 4 x^{- 4 - 1}) : \frac{56}{x ^{5}}

= \frac{56}{x ^{5}}
