展开 ((\sqrt[3]{x}(2+9x^{2/3}))/2)+x(ln(x)+1)

解答

展开

\frac{3 x ( 2 + 9 x ^{\frac{2}{3}} )}{2} + x (ln (x) + 1)

3 x + \frac{9 3 x x ^{\frac{2}{3}}}{2} + x ln (x) + x

求解步骤

\frac{3 x ( 2 + 9 x ^{\frac{2}{3}} )}{2} + x (ln (x) + 1)

乘开

x (ln (x) + 1) : x ln (x) + x

= \frac{3 x ( 2 + 9 x ^{\frac{2}{3}} )}{2} + x ln (x) + x

化简

\frac{3 x ( 2 + 9 x ^{\frac{2}{3}} )}{2} + x ln (x) + x : 3 x + \frac{9 3 x x ^{\frac{2}{3}}}{2} + x ln (x) + x

= 3 x + \frac{9 3 x x ^{\frac{2}{3}}}{2} + x ln (x) + x

\frac{\partial}{\partial y} ((f (y, x)) (2 x + 2 y))

e x p an d A (6, - 2)

\frac{\partial}{\partial y} ((M) (y^{3} + k x y^{4} - 2 x))

e x p an d (-) (x + 1) (- x + 3)

e x p an d \frac{p ( s - 2 )}{2}
