(- 1 - 3) + i (1 - 3)

(- 1 - 3) + i (1 - 3)

求解步骤

(- 1 - 3) + i (1 - 3)

乘开

i (1 - 3) : i (1 - 3)

= (- 1 - 3) + i (1 - 3)

s im pl i f y (1 - \frac{1}{( x + 3 )}) (1 - \frac{1}{x + 2}) (1 - \frac{1}{x + 1})

s im pl i f y (\frac{3173}{126})^{2} \cdot (\frac{1}{( 47 ) ^{2}} + \frac{1}{( 79 ) ^{2}} \cdot 1.9)

e x p an d \frac{4 ( x + 6 ) ^{5}}{x ^{3}}

e x p an d 5 (8 + 36)

e x p an d \frac{2 s ^{2} + 2}{s ^{2} ( s ^{2} + 5 )}
