化简 6x^2+(768)/x

解答

化简

6 x^{2} + \frac{768}{x}

\frac{6 x ^{3} + 768}{x}

求解步骤

6 x^{2} + \frac{768}{x}

使用分式法则:

a + \frac{b}{c} = \frac{a c + b}{c}

= \frac{6 x ^{2} x + 768}{x}

化简

x^{2} x : x^{3}

= \frac{6 x ^{3} + 768}{x}

x \to + 1 lim (\frac{- 1}{x - 1})

\frac{d}{d x} (\frac{ln ( x ^{3} + 1 )}{2 ^{x^{4}} - 6})

\int \frac{1}{1 - u} d u

\int e^{7 x + 8} d x
