问题描述:
0.5乘0.32乘1.25乘0.025乘2的简便运算
答
0.5乘0.32乘1.25乘0.025乘2
=0.5×0.4×0.8×1.25×0.025×2
=0.2×1×0.05
=0.01×1
=0.01
答
=0.5×2×0.4×0.4×1.25×0.025×2
=(0.5×2)×(0.4×0.025)×(0.4×1.25×2)
=1×0.01×1
=0.01
=
答
0.5*0.32*1.25*0.025*2=(0.5*2)*0.4*0.8*1.25*0.025=(0.5*2)*(0.8*1.25)*(0.4*0.025)=1*1*0.01=0.01
答
=0.5*2*0.04*8*1.25*0.025=1*0.04*10*0.025=0.4*0.025=0.01
