derivative ln(x^{61})

解

導関数

ln (x^{61})

解

\frac{61}{x}

解答ステップ

\frac{d}{d x} (ln (x^{61}))

連鎖法則を適用:

\frac{1}{x ^{61}} \frac{d}{d x} (x^{61})

= \frac{1}{x ^{61}} \frac{d}{d x} (x^{61})

\frac{d}{d x} (x^{61}) = 61 x^{60}

= \frac{1}{x ^{61}} \cdot 61 x^{60}

簡素化

\frac{1}{x ^{61}} \cdot 61 x^{60} : \frac{61}{x}

= \frac{61}{x}
