derivative sqrt(7x+8)

解

導関数

7 x + 8

解

\frac{7}{2 7 x + 8}

解答ステップ

\frac{d}{d x} (7 x + 8)

連鎖法則を適用:

\frac{1}{2 7 x + 8} \frac{d}{d x} (7 x + 8)

= \frac{1}{2 7 x + 8} \frac{d}{d x} (7 x + 8)

\frac{d}{d x} (7 x + 8) = 7

= \frac{1}{2 7 x + 8} \cdot 7

簡素化

\frac{1}{2 7 x + 8} \cdot 7 : \frac{7}{2 7 x + 8}

= \frac{7}{2 7 x + 8}
