1.25*0.7*0.9*0.8=(1.25*0.8)*(0.7*0.9)=1*0.63=0.63
20.862再问:过程再问:54.9×0.38==
0.8×33×1.25=0.8×1.25×33=1×33=33
4.05-0.8-0.7=4.05-(0.8+0.7)=4.05-1.5=2.55
3.5*1.25+1.25+3.5/0.8=3.5*1.25+1.25+3.5*1.25=1.25*(3.5+1+3.5)=1.25*8=10
0.8*65.18*1.25=0.8×1.28×65.18=1×65.18=65.18
0.52*1=0.52再答:因为1.25*0.8=1
0.35*(1.25*0.8)=0.35*1=0.35
8.75÷4/5÷5/4=8.75×5/4×4/5=8.75×(5/4×4/5)=8.75
1.25×39.8×0.8=1.25×0.8×39.8=1×39.8=39.83.6×0.7×2.5=0.9×4×0.7×2.5=4×2.5×0.9×0.7=10×0.63=6.3
1、1.25×1.25.×0.8×0.820个1.2521个0.8=(1.25×0.8)×(1.25×0.8)×...×(1.25×0.8)×0.8=1×1×......×1×0.8=0.82、0.1
1.25x0.7x0.8=1.25x0.8x0.7=1x0.7=0.7再问:谢了
8x1.25+0.8x1.25=10+1=11
我今晚也是这作业,我只会4题,也在问再问:哦再答: 再问:同病相怜再问:我也只会这四题再答: 再问:4.05+37.85
比较大小0.8x(-2.2),3x(-0.7),1.25x(1.3)0.8x(-2.2)=-1.763x(-0.7)=-2.11.25x(1.3)=1.625∵-2.1<-1.76<1.625∴3x(
是不是0.7乘以0.再问:是再答:如果是一个乘法的话,我像结果是0.56。
1.25*0.8*0.7=0.7
0.7÷1.25=0.7÷10/8=0.7×8÷10=5.6÷10=0.56
a=0.8^(-2)=(5/4)^2b=3^(-0.7)=(1/3)^0.7c=1.25^1.3=(5/4)^1.3对于a,c明显c
