(3 a^{2} c) 3

9 a^{2} c

求解步骤

(3 a^{2} c) \cdot 3

去除括号:

(a) = a

= 3 a^{2} c \cdot 3

数字相乘:

3 \cdot 3 = 9

= 9 a^{2} c

e x p an d (2 T - 1) (π + 5)

e x p an d (\frac{5 π}{12} - \frac{1}{4}) 100

e x p an d (1 + 9.7 e^{- 0.4 x})^{2}

e x p an d 5 (x + 5 = 2 x + 40)

e x p an d \frac{z d}{( z - 1 ) ( z - 1.01 )}
