解答

展开

(1 + 2 x)^{0.5} (2 x) (x^{2} + 1)^{\frac{1}{3}}

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

求解步骤

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

(a) = a

= (1 + 2 x)^{\frac{1}{2}} \cdot 2 x (x^{2} + 1)^{\frac{1}{3}}

e x p an d F (0.3) D (y = - 3)

e x p an d lo g_{7} (w)

e x p an d \frac{2 x ^{2} - x + 8}{( x ^{2} + 4 ) ^{2}}

e x p an d \frac{x ^{3} + x ^{2} + 1}{x ( x - 1 ) ( x ^{2} + x + 1 ) ( x ^{2} + 1 ) ^{2}}

e x p an d \frac{( 0.2 - x )}{( 0.2 + x ) x}
