derivative f(x)=x^{1.7}

解答

导数

f (x) = x^{1.7}

1.7 x^{0.7}

求解步骤

\frac{d}{d x} (x^{1.7})

使用幂法则:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= 1.7 x^{1.7 - 1}

化简

= 1.7 x^{0.7}

x \to - 4 lim (\frac{x ^{2} + 9}{x + 2})

\int 16 e^{u} d u

y^{^{''}} - 4 y^{^{'}} - x + 2 = 0

\frac{d}{d x} (x^{3} + 2 x^{2} - 4 x - 8)

x \to 4 lim (3 e^{1.7 x} + 1)
