5.28x0.29一0.29x4.28简便运算

你好!5.28x0.29一0.29x4.28简便运算=(5.28-4.28)x0.29=1x0.29=0.29仅代表个人观点,不喜勿喷,谢谢.

解:采用分配律,原式=28X0.29一0.29X0.28=0.29x(28-0.28)=0.29x27.72= 8.0388

解1.28x0.29-0.29x0.28=(1.28x-0.28)x0.29=1x0.29=0.29

1.28*0.29-0.29*0.28=0.29*(1.28-0.28)=0.29*1=0.29

13.54x0.29-0.29x3.54=(13.54-3.54)*0.29=10*0.29=2.9

3.54*0.29-0.29*2.54=0.29*(3.54-2.54)=0.29*1=0.29

0.29*(3.54-2.54)

你好!第一题:=(1.28-0.28)x0.29=1x0.29=0.29 仅代表个人观点,不喜勿喷,谢谢.

3.54*0.29-0.29*2.54简便计算=(3.54-2.54)x0.29=1x0.29=0.29

0.29x100.2=0.29x(100+0..2)=0.29x100+0.29x0.2=29+0.058=29.058
