(d^2)/(dx^2)(1/(x^9))

Solution

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x ^{9}})

Solution

\frac{90}{x ^{11}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x ^{9}})

\frac{d}{d x} (\frac{1}{x ^{9}}) = - \frac{9}{x ^{10}}

= \frac{d}{d x} (- \frac{9}{x ^{10}})

\frac{d}{d x} (- \frac{9}{x ^{10}}) = \frac{90}{x ^{11}}

= \frac{90}{x ^{11}}
