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

\frac{4}{8 x + 1}

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

\frac{1}{2 8 x + 1} \cdot 8 : \frac{4}{8 x + 1}

= \frac{4}{8 x + 1}
