derivative of \sqrt[4]{5/4 x}

解答

\frac{d}{d x} (4 \frac{5}{4} x)

\frac{5 ^{\frac{1}{4}}}{4 2 x ^{\frac{3}{4}}}

求解步骤

\frac{d}{d x} (4 \frac{5}{4} x)

使用连锁律:

\frac{1}{4 ( \frac{5}{4} x ) ^{\frac{3}{4}}} \frac{d}{d x} (\frac{5}{4} x)

= \frac{1}{4 ( \frac{5}{4} x ) ^{\frac{3}{4}}} \frac{d}{d x} (\frac{5}{4} x)

\frac{d}{d x} (\frac{5}{4} x) = \frac{5}{4}

= \frac{1}{4 ( \frac{5}{4} x ) ^{\frac{3}{4}}} \cdot \frac{5}{4}

化简

\frac{1}{4 ( \frac{5}{4} x ) ^{\frac{3}{4}}} \cdot \frac{5}{4} : \frac{5 ^{\frac{1}{4}}}{4 2 x ^{\frac{3}{4}}}

= \frac{5 ^{\frac{1}{4}}}{4 2 x ^{\frac{3}{4}}}

\int \frac{1}{x ^{2} - 2 x + 26} d x

x^{^{''}} - a x = 0

x \to 0 lim (x^{2} cos (\frac{8}{x}))
