(d^2)/(dx^2)(7x^{-3}+5t^{-8/3})

\frac{d ^{2}}{d x ^{2}} (7 x^{- 3} + 5 t^{- \frac{8}{3}})

\frac{84}{x ^{5}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (7 x^{- 3} + 5 t^{- \frac{8}{3}})

\frac{d}{d x} (7 x^{- 3} + 5 t^{- \frac{8}{3}}) = - \frac{21}{x ^{4}}

= \frac{d}{d x} (- \frac{21}{x ^{4}})

\frac{d}{d x} (- \frac{21}{x ^{4}}) = \frac{84}{x ^{5}}

= \frac{84}{x ^{5}}

\int_{0}^{1} (3 x)^{2} d x

\frac{4 s - 18}{s ^{2} - 6 s + 10}

y = x + 5

\frac{d y}{d x} + a y = 0

x \to - 2 lim (3 x^{4} + 2 x^{2} - x + 1)
