展开 ex(3-i)^6

解答

展开

e x (3 - i)^{6}

- 352 e x - 936 e i x

求解步骤

e x (3 - i)^{6}

(3 - i)^{6} = - 352 - 936 i

= e (- 352 - 936 i) x

= e (- 352 - 936 i) x

使用分配律:

a (b - c) = ab - a c

a = e x, b = - 352, c = 936 i

= e x (- 352) - e x \cdot 936 i

使用加减运算法则

+ (- a) = - a

= - 352 e x - 936 e i x

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

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

e x p an d 2 - (4 (- 2) \cdot 5)

e x p an d \frac{RT V - a}{V ( V - b )}

e x p an d 52 e^{4 x} - 4 (13 e^{4 t} - 11)
