59x10.1简便计算怎么做

5.2X10.1 =5.2*(10+0.1) =5.2*10+5.2*0.1 =52+0.52 =52.52

=(7-0.2)*(10+0.1)=7*10-0.2*10+7*0.1-0.2*0.1=70-2+0.7-0.02=68+0.68=68.68

83x10.1用简便方法计算;83*10.1=83*(10+0.1)=83*10+83*0.1=830+8.3=838.3

=5.3*(10+0.1)=5.3*10+5.3*0.1=53+0.53=53.53

9.6*10.1=9.6*(10+0.1)=9.6*10+9.6*0.1=96+0.96=96.96

=(10-0.1)^2*(10+0.1)^2=(100+0.01-2)*(100+0.01+2)=(100.01-2)(100.01+2) 平方差公式=(100.01)^2-4=(100+0.01)^2-4=10000+0.0001+2-4=9998.0001

1.1X10.1一1.1 =1.1X(10.1-1) =1.1X9.1 =(1+0.1)X9.1 =1X9.1+0.1X9.1 =9.1+0.91 =10.01

4.9*101=4.9*(100+1)=490+4.9=494.9或:4.9*101=(5-0.1*101=505-10.1=494.9

36*10.1=36*(10+0.1)=36*10+36*0.1=360+3.6=363.6

你好,很高兴为你解答3.7*10.1-0.37简便运算怎么做=0.37x101-0.37=0.37x(101-1)=37 满意采纳哦!!
