10.1x5.2%0.52怎么简便运算

原式=101×0.52-0.52×1 =0.52×(101-1) =0.52×100 =52

=5.2×10.1-5.2×0.1 =5.2(10-1-0.1) =5.2×10 =52

5.2×10.1- 0.52 =0.52×101- 0.52×1 =0.52×(101-1) =0.52×100 =52

(5十0.2)X(10十0.1)=50十0.5十2十0.02二52.52

10.1*5.2-0.52 =(10+0.1)*5.2-0.52 =52+0.52-0.52 =52

5.2乘10.1 =5.2x(10+0.1) =5.2x10+5.2x0.1 =52+0.52 =52.52

10.1×1.05-2.52÷24 =(10+0.1)x1.05-2.52÷6÷4 =10x1.05+0.1x1.05-0.42÷4 =10.5+0.105-0.105 =10.5

5.2x10.1 =5.2x10+5.2x0.1 =52+0.52 =52.52

5.2×10.1 =5.2×10+5.2×0.1 =52+0.52 =52.52

20.5×10.1-2.05 =20.5x10.1-20.5x0.1 =20.5x(10.1-0.1) =20.5x10 =205 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。
