(d^2)/(dx^2)(x^4-6x^3)

解答

\frac{d ^{2}}{d x ^{2}} (x^{4} - 6 x^{3})

12 x^{2} - 36 x

求解步骤

\frac{d ^{2}}{d x ^{2}} (x^{4} - 6 x^{3})

\frac{d}{d x} (x^{4} - 6 x^{3}) = 4 x^{3} - 18 x^{2}

= \frac{d}{d x} (4 x^{3} - 18 x^{2})

\frac{d}{d x} (4 x^{3} - 18 x^{2}) = 12 x^{2} - 36 x

= 12 x^{2} - 36 x
