derivative of

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

\frac{2}{( 3 - x ) ^{3}}

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{d}{d x} (3 - x) = - 1

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

Simplify

= \frac{2}{( 3 - x ) ^{3}}
