\frac{d}{d x} (- \frac{64}{( 1 + 8 x ) ^{2}})

\frac{1024}{( 1 + 8 x ) ^{3}}

Solution steps

\frac{d}{d x} (- \frac{64}{( 1 + 8 x ) ^{2}})

Take the constant out:

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

= - 64 \frac{d}{d x} (\frac{1}{( 1 + 8 x ) ^{2}})

Apply exponent rule:

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

= - 64 \frac{d}{d x} ((1 + 8 x)^{- 2})

Apply the chain rule:

- \frac{2}{( 1 + 8 x ) ^{3}} \frac{d}{d x} (1 + 8 x)

= - \frac{2}{( 1 + 8 x ) ^{3}} \frac{d}{d x} (1 + 8 x)

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

= - 64 (- \frac{2}{( 1 + 8 x ) ^{3}} \cdot 8)

Simplify

- 64 (- \frac{2}{( 1 + 8 x ) ^{3}} \cdot 8) : \frac{1024}{( 1 + 8 x ) ^{3}}

= \frac{1024}{( 1 + 8 x ) ^{3}}
