derivative of

f (x) = \frac{66}{( 1 - x ) ^{4}}

\frac{264}{( 1 - x ) ^{5}}

Solution steps

\frac{d}{d x} (\frac{66}{( 1 - x ) ^{4}})

Take the constant out:

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

= 66 \frac{d}{d x} (\frac{1}{( 1 - x ) ^{4}})

Apply exponent rule:

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

= 66 \frac{d}{d x} ((1 - x)^{- 4})

Apply the chain rule:

- \frac{4}{( 1 - x ) ^{5}} \frac{d}{d x} (1 - x)

= - \frac{4}{( 1 - x ) ^{5}} \frac{d}{d x} (1 - x)

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

= 66 (- \frac{4}{( 1 - x ) ^{5}} (- 1))

Simplify

66 (- \frac{4}{( 1 - x ) ^{5}} (- 1)) : \frac{264}{( 1 - x ) ^{5}}

= \frac{264}{( 1 - x ) ^{5}}
