derivative 1/(2sqrt(x))+1/(3x^{2/3)}

解

導関数

\frac{1}{2 x} + \frac{1}{3 x ^{\frac{2}{3}}}

- \frac{1}{4 x ^{\frac{3}{2}}} - \frac{2}{9 x ^{\frac{5}{3}}}

解答ステップ

\frac{d}{d x} (\frac{1}{2 x} + \frac{1}{3 x ^{\frac{2}{3}}})

和/差の法則を適用:

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

= \frac{d}{d x} (\frac{1}{2 x}) + \frac{d}{d x} (\frac{1}{3 x ^{\frac{2}{3}}})

\frac{d}{d x} (\frac{1}{2 x}) = - \frac{1}{4 x ^{\frac{3}{2}}}

\frac{d}{d x} (\frac{1}{3 x ^{\frac{2}{3}}}) = - \frac{2}{9 x ^{\frac{5}{3}}}

= - \frac{1}{4 x ^{\frac{3}{2}}} - \frac{2}{9 x ^{\frac{5}{3}}}
