derivative of-8/(x^3+2/(x^2))

解

\frac{d}{d x} (- \frac{8}{x ^{3}} + \frac{2}{x ^{2}})

解

\frac{24}{x ^{4}} - \frac{4}{x ^{3}}

解答ステップ

\frac{d}{d x} (- \frac{8}{x ^{3}} + \frac{2}{x ^{2}})

和/差の法則を適用:

(f \pm g)^{'} = f^{'} \pm g^{'}

= - \frac{d}{d x} (\frac{8}{x ^{3}}) + \frac{d}{d x} (\frac{2}{x ^{2}})

\frac{d}{d x} (\frac{8}{x ^{3}}) = - \frac{24}{x ^{4}}

\frac{d}{d x} (\frac{2}{x ^{2}}) = - \frac{4}{x ^{3}}

= - (- \frac{24}{x ^{4}}) - \frac{4}{x ^{3}}

簡素化

= \frac{24}{x ^{4}} - \frac{4}{x ^{3}}
