41×9.9+4.1怎么简便算
简便计算:41*9.9+4.1 要全部过程! -
41*9.9+4.1 =4.1*99+4.1*1 =4.1*(99+1)=4.1*100 =410
41×9.9+4.1=4.1x99+4.1=4.1x（99+1）410
41*9.9+4.1 =4.1*99+4.1*1 =4.1*(99+1)=4.1*100 =410
41×9.9+4.1=4.1x99+4.1=4.1x（99+1）410
=41×9.9＋41×0.1 =41×(9.9＋0.1)=41×10 =410
41*9.9+4.1 =4.1X(99+1)=4.1X100 =410
41×9.9+4.1的简便运算 -
41乘以9.9加41乘以0.1等于41乘以10等于410
4.1x9.9 =4.1x（10-0.1）41-0.41 =40.59
4.1*9.9 4.1*0.1怎样简便运算 -
4.1*9.9=(4+0.1)*(10-0.1)=4*10+0.1*10-4*.01-0.1*0.1 =40+1-0.4-0.01 =40.59 4.1*0.01=4.1/100=0.041
回答：49×(9.9+0.1)
分数线下面是算式上面也是算式怎么简便运算? -
第一题，9.78*(99+1)=9.78*100=978 第二题，5.7*(10+0.1)=5.7*10+5.7*0.1=57.57 第三题，12.5*0.8*4.1=10*4.1=41 第四题，3.54*(9.9+1)+0.1=3.54*10.9+0.1=38.686 第五题，5.6*(1+0.25)=5.6+5.6*0.25=7 第六题，25*(16.7-0.7)=25*16到此结束了？。
4.9×9.9+4.1×0.1 =4.9×（10-0.1）0.41 =49-0.49+0.41 =49-（0.49-0.41）49-0.08 =48.92
