第一题
=54×10.8
=583.2
第二题
=3.32×0.8
=2.656
第三题
0.175×1
=0.175
第4题
=0.175*（0.25*0.4）
=0.175*0.1
=0.0175

54*（3.94+6.86) =54×10.8=583.2
(3.2+0.12)*0.8 =2.656
0.175*0.25×4 =0.175*（0.25×4）=0.175×1=0.175
0.175*0.25*0.4=0.175*（0.25*0.4）=0.175×0.1=0.0175

54*（3.94+6.86)
=54×10.8
=583.2

(3.2+0.12)*0.8
=3.32×0.8
=2.656

0.175*0.25×4
=0.175×1
=0.175
额，最后两题重复了。。。。。。望采纳！
