34.8*6.3+473*0.37+13*5.25怎简便做
34.8*6.3+473*0.37+13*1.25
=34.8*6.3+47.3*3.7+13*1.25
=34.8*6.3+34.8*3.7+12.5*3.7+1.3*12.5
=34.8*(6.3+3.7)+12.5*(3.7+1.3)
=34.8*10+12.5*5
=348+62.5
=410.5
再问： 是34.8*6.3+473*0.37+13*5.25请指教
再答： 34.8*6.3+473*0.37+13*5.25 =34.8*6.3+47.3*3.7+13*1.25+13*4 =34.8*6.3+34.8*3.7+12.5*3.7+1.3*12.5+52 =34.8*(6.3+3.7)+12.5*(3.7+1.3)+52 =34.8*10+12.5*5+52 =348+62.5+52 =410.5+52 =462.5
=34.8*6.3+47.3*3.7+13*1.25
=34.8*6.3+34.8*3.7+12.5*3.7+1.3*12.5
=34.8*(6.3+3.7)+12.5*(3.7+1.3)
=34.8*10+12.5*5
=348+62.5
=410.5
再问： 是34.8*6.3+473*0.37+13*5.25请指教
再答： 34.8*6.3+473*0.37+13*5.25 =34.8*6.3+47.3*3.7+13*1.25+13*4 =34.8*6.3+34.8*3.7+12.5*3.7+1.3*12.5+52 =34.8*(6.3+3.7)+12.5*(3.7+1.3)+52 =34.8*10+12.5*5+52 =348+62.5+52 =410.5+52 =462.5
