e (t - 2.36)

e t - 6.41514 \dots

求解步骤

e (t - 2.36)

使用分配律:

a (b - c) = ab - a c

a = e, b = t, c = 2.36

= e t - e 2.36

= e t - 2.36 e

数字相乘:

2.36 \cdot 2.71828 \dots = 6.41514 \dots

= e t - 6.41514 \dots

e x p an d so l v e (- 1575000 + \frac{x}{1 + ( 0.2139600000000 \dots ) ^{2}} = 0)

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

e x p an d 92.34 (x - 0.3) (1 - 0, 4 (\frac{x - 0.3}{0.5 x}))

e x p an d (x + y e^{w}) (- e^{w} - 1)

e x p an d (4 x y^{2} - 6 y) d y
