derivative of

\frac{1}{x - 8}

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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