(d^2)/(dx^2)(1/(x^7))

Solution

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x ^{7}})

Solution

\frac{56}{x ^{9}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x ^{7}})

\frac{d}{d x} (\frac{1}{x ^{7}}) = - \frac{7}{x ^{8}}

= \frac{d}{d x} (- \frac{7}{x ^{8}})

\frac{d}{d x} (- \frac{7}{x ^{8}}) = \frac{56}{x ^{9}}

= \frac{56}{x ^{9}}
