derivative-9/((6t+8)^{3/2)}

解

導関数

- \frac{9}{( 6 t + 8 ) ^{\frac{3}{2}}}

解

\frac{81}{( 6 t + 8 ) ^{\frac{5}{2}}}

解答ステップ

\frac{d}{d t} (- \frac{9}{( 6 t + 8 ) ^{\frac{3}{2}}})

定数を除去:

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

= - 9 \frac{d}{d t} (\frac{1}{( 6 t + 8 ) ^{\frac{3}{2}}})

指数の規則を適用する:

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

= - 9 \frac{d}{d t} ((6 t + 8)^{- \frac{3}{2}})

連鎖法則を適用:

- \frac{3}{2 ( 6 t + 8 ) ^{\frac{5}{2}}} \frac{d}{d t} (6 t + 8)

= - \frac{3}{2 ( 6 t + 8 ) ^{\frac{5}{2}}} \frac{d}{d t} (6 t + 8)

\frac{d}{d t} (6 t + 8) = 6

= - 9 (- \frac{3}{2 ( 6 t + 8 ) ^{\frac{5}{2}}} \cdot 6)

簡素化

- 9 (- \frac{3}{2 ( 6 t + 8 ) ^{\frac{5}{2}}} \cdot 6) : \frac{81}{( 6 t + 8 ) ^{\frac{5}{2}}}

= \frac{81}{( 6 t + 8 ) ^{\frac{5}{2}}}
