化简 (4(3x^{2/3}\sqrt[3]{x}-2(x+1)))/(9\sqrt[3]{x)x^{4/3}}

解答

化简

\frac{4 ( 3 x ^{\frac{2}{3}} 3 x - 2 ( x + 1 ) )}{9 3 x x ^{\frac{4}{3}}}

\frac{4 ( x - 2 )}{9 x ^{\frac{5}{3}}}

求解步骤

\frac{4 ( 3 x ^{\frac{2}{3}} 3 x - 2 ( x + 1 ) )}{9 3 x x ^{\frac{4}{3}}}

化简

3 x^{\frac{2}{3}} 3 x - 2 (x + 1) : x - 2

= \frac{4 ( x - 2 )}{9 3 x x ^{\frac{4}{3}}}

化简

9 3 x x^{\frac{4}{3}} : 9 x^{\frac{5}{3}}

= \frac{4 ( x - 2 )}{9 x ^{\frac{5}{3}}}

e x p an d \frac{26}{( x - 1 ) ( x + 1 )}

e x p an d \frac{1}{25} (5 x sin (5 x) + cos (5 x)) + C

e x p an d (x + 2)^{2}

e x p an d (x y + y^{2}) d y + (y^{2} + 1) d x
