化简 2+{(9-3)/3 (8/(6/3)-10)}

解答

化简

2 + {\frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10)}

- 10

求解步骤

2 + (\frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10))

使用法则:

(a) = a

(\frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10)) = \frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10)

= 2 + \frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10)

\frac{9 - 3}{3} (\frac{8}{\frac{6}{3}} - 10) = - 12

= 2 - 12

数字相减:

2 - 12 = - 10

= - 10
