化简 (5\sqrt[3]{x}+5)(\sqrt[3]{x}+1)

解答

化简

(5 3 x + 5) (3 x + 1)

5 (3 x)^{2} + 10 3 x + 5

求解步骤

(5 3 x + 5) (3 x + 1)

Apply FOIL method

(5 3 x + 5) (3 x + 1) : 5 (3 x)^{2} + 10 3 x + 5

= 5 (3 x)^{2} + 10 3 x + 5

s im pl i f y (3 - 2 i)^{5}

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

s im pl i f y (- 2 + 4 i)^{13}

e x p an d A (5, - 2) B (2, 4)

f (s) = \frac{6}{( s - 2 ) ^{4} ( s ^{2} - 4 s + 4 )}
