derivative of

\frac{1}{( x ^{2} + 8 ) ^{5}}

- \frac{10 x}{( x ^{2} + 8 ) ^{6}}

Solution steps

\frac{d}{d x} (\frac{1}{( x ^{2} + 8 ) ^{5}})

Apply exponent rule:

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

= \frac{d}{d x} ((x^{2} + 8)^{- 5})

Apply the chain rule:

- \frac{5}{( x ^{2} + 8 ) ^{6}} \frac{d}{d x} (x^{2} + 8)

= - \frac{5}{( x ^{2} + 8 ) ^{6}} \frac{d}{d x} (x^{2} + 8)

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

= - \frac{5}{( x ^{2} + 8 ) ^{6}} \cdot 2 x

Simplify

- \frac{5}{( x ^{2} + 8 ) ^{6}} \cdot 2 x : - \frac{10 x}{( x ^{2} + 8 ) ^{6}}

= - \frac{10 x}{( x ^{2} + 8 ) ^{6}}

\int \frac{x ^{3} e ^{x} - 2 x ^{2}}{x ^{3}} d x

\int p (p + 6)^{6} d p

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

\int \frac{x ^{2}}{( 4 - x ^{2} ) ^{\frac{5}{2}}} d x

\int 5 \frac{x}{16 - x ^{2}} d x
