(d^4)/(dx^4)(3x^4)

解答

\frac{d ^{4}}{d x ^{4}} (3 x^{4})

72

求解步骤

\frac{d ^{4}}{d x ^{4}} (3 x^{4})

\frac{d}{d x} (3 x^{4}) = 12 x^{3}

= \frac{d ^{3}}{d x ^{3}} (12 x^{3})

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

= \frac{d ^{2}}{d x ^{2}} (36 x^{2})

\frac{d}{d x} (36 x^{2}) = 72 x

= \frac{d}{d x} (72 x)

\frac{d}{d x} (72 x) = 72

= 72
