(3 x + 2) e^{3}

3 e^{3} x + 2 e^{3}

求解步骤

(3 x + 2) e^{3}

= e^{3} (3 x + 2)

使用分配律:

a (b + c) = ab + a c

a = e^{3}, b = 3 x, c = 2

= e^{3} \cdot 3 x + e^{3} \cdot 2

= 3 e^{3} x + 2 e^{3}

e x p an d - \frac{3 ( 16 + 58 )}{11}

e x p an d - 8 (- 5 x - 7 y = - 12)

e x p an d \frac{1}{( rc x + 1 ) s}

e x p an d 3 ((1, 1, - 1) - 2 (0, 0, 4))

e x p an d (4, 6, 8) \cdot (3, x, - 5)
