-3 2 -(-6)2除以(-2/3) -6 2-(-12)除以(-2/3) -3 2-(-6 2)除以(-2/3)

问题描述:

-3 2 -(-6)2除以(-2/3) -6 2-(-12)除以(-2/3) -3 2-(-6 2)除以(-2/3)
1.
-3 2 -(-6)2除以(-2/3)
2.
-6 2-(-12)除以(-2/3)
3.
-3 2-(-6 2)除以(-2/3)

还是看不明白这是几个题目

你最好加上序号

当作一个题目计算如下:

-3² -(-6)²除以(-2/3) -6²-(-12)除以(-2/3) -3²-(-6²)除以(-2/3)

=-9+36×3/2-36-12×3/2-9-36×3/2

=-9+54-36-18-9-54

=54-54-36-18-9-9

=-72

1.
-3 2 -(-6)2除以(-2/3)
2.
-6 2-(-12)除以(-2/3)
3.
-3 2-(-6 2)除以(-2/3)
下次会注意的。。。1、
-3² -(-6)²除以(-2/3)
=-9+36×3/2
=-9+54
=45


2.
-6 2-(-12)除以(-2/3)
=-36-12×3/2
=-36-18
=-54



3.
-3 2-(-6 2)除以(-2/3)
=-9-36×3/2
=-9-54
=-63
