\frac{d}{d x} (\frac{1}{1 - 4 x})

\frac{4}{( 1 - 4 x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{1}{1 - 4 x})

Apply exponent rule:

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

= \frac{d}{d x} ((1 - 4 x)^{- 1})

Apply the chain rule:

- \frac{1}{( 1 - 4 x ) ^{2}} \frac{d}{d x} (1 - 4 x)

= - \frac{1}{( 1 - 4 x ) ^{2}} \frac{d}{d x} (1 - 4 x)

\frac{d}{d x} (1 - 4 x) = - 4

= - \frac{1}{( 1 - 4 x ) ^{2}} (- 4)

Simplify

- \frac{1}{( 1 - 4 x ) ^{2}} (- 4) : \frac{4}{( 1 - 4 x ) ^{2}}

= \frac{4}{( 1 - 4 x ) ^{2}}
