(d^2)/(dx^2)((x^2+8)^9)

\frac{d ^{2}}{d x ^{2}} ((x^{2} + 8)^{9})

18 ((x^{2} + 8)^{8} + 16 x^{2} (x^{2} + 8)^{7})

Solution steps

\frac{d ^{2}}{d x ^{2}} ((x^{2} + 8)^{9})

\frac{d}{d x} ((x^{2} + 8)^{9}) = 18 x (x^{2} + 8)^{8}

= \frac{d}{d x} (18 x (x^{2} + 8)^{8})

\frac{d}{d x} (18 x (x^{2} + 8)^{8}) = 18 ((x^{2} + 8)^{8} + 16 x^{2} (x^{2} + 8)^{7})

= 18 ((x^{2} + 8)^{8} + 16 x^{2} (x^{2} + 8)^{7})
