\frac{1}{3} (6)^{3} - 5 (6)^{2} + 24 (6)

36

求解步骤

\frac{1}{3} \cdot 6^{3} - 5 \cdot 6^{2} + 24 (6)

去除括号:

(a) = a

= \frac{1}{3} \cdot 6^{3} - 5 \cdot 6^{2} + 24 \cdot 6

\frac{1}{3} \cdot 6^{3} = 72

24 \cdot 6 = 144

= 72 - 6^{2} \cdot 5 + 144

数字相加:

72 + 144 = 216

= 216 - 6^{2} \cdot 5

6^{2} \cdot 5 = 180

= 216 - 180

数字相减:

216 - 180 = 36

= 36
