化简 (sqrt(x)-8)(\sqrt[3]{x}+4)

解答

化简

(x - 8) (3 x + 4)

6 x^{5} + 4 x - 8 3 x - 32

求解步骤

(x - 8) (3 x + 4)

Apply FOIL method

(x - 8) (3 x + 4) : x^{\frac{5}{6}} + 4 x - 8 3 x - 32

= x^{\frac{5}{6}} + 4 x - 8 3 x - 32

x^{\frac{5}{6}} = 6 x^{5}

= 6 x^{5} + 4 x - 8 3 x - 32

e x p an d (11 + 3) \cdot 11

s im pl i f y (m + \frac{9}{5}) (m - \frac{9}{5})

e x p an d x^{\frac{1}{2}} (x^{4} - 2 x^{2} + 1)

e x p an d π (x^{4} - 2 x^{2} + 1) - (x - 2 x = 1)

e x p an d [\frac{2 x ^{2} + 6 x + 5}{( x ^{2} + 3 x + 2 ) ^{2}}]
