derivative of

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

- \frac{80 ( x + 8 ) ^{4}}{( x - 8 ) ^{6}}

Solution steps

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

Apply the chain rule:

5 (\frac{x + 8}{x - 8})^{4} \frac{d}{d x} (\frac{x + 8}{x - 8})

= 5 (\frac{x + 8}{x - 8})^{4} \frac{d}{d x} (\frac{x + 8}{x - 8})

\frac{d}{d x} (\frac{x + 8}{x - 8}) = - \frac{16}{( x - 8 ) ^{2}}

= 5 (\frac{x + 8}{x - 8})^{4} (- \frac{16}{( x - 8 ) ^{2}})

Simplify

5 (\frac{x + 8}{x - 8})^{4} (- \frac{16}{( x - 8 ) ^{2}}) : - \frac{80 ( x + 8 ) ^{4}}{( x - 8 ) ^{6}}

= - \frac{80 ( x + 8 ) ^{4}}{( x - 8 ) ^{6}}
