14.8*6.3-6.3*6.5+8.3*3.7 简便计算 谢谢

14.8*6.3-6.3*6.5+8.3*3.7=6.3*(14.8-6.5+3.7)+2*3.7=6.3*12+2*3.7=6.3*10+2*(6.3+3.7)=63+20=83

14.8*6.3-6.3*6.5+8.3*3.7=(14.8-6.5)x6.3+8.3x3.7=8.3x6.3+8.3x3.7=8.3x(6.3+3.7)=8.3x10=83

原式=6.3*(14.8-6.5)+0.465*(450+550)+8.3*3.7 =6.3*8.3+0.465*1000+8.3*3.7 =(6.3+3.7)*8.3+465 =83+465 =548

14.8x6.3-6.3x6.5+8.3x3.7;=6.3x(14.8-6.5)+8.3x3.7;=6.3x8.3+8.3x3.7;=8.3x(6.3+3.7);=8.3x10;=83

原式=6.3*(14.8-6.5)+0.465*(450+550)+8.3*3.7 =6.3*8.3+0.465*1000+8.3*3.7 =(6.3+3.7)*8.3+465 =83+465 =548

14.8*6.3-6.3*6.5+8.5*3.7=6.3x(14.8-6.5)+8.5x3.7=6.3x8.3+8.5x3.7=8.3x(6.3+3.7)+0.2x3.7=8.3x10+0.74=83.74

14.8x6.3-6.3x6.5+8.4x3.7=(14.8-6.5)x6.3+8.4x3.7=8.3x6.3+8.4x3.7=(8.4-0.1)x6.3+8.4x3.7=8.4x6.3-0.1x6.3+8.4x3.7=8.4x(6.3+3.7)-0.63=8.4x10-0.63=84-0.63=83.37 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢

=3.7*4*6.3+8.3*3.7=3.7*25.2+8.3*3.7=3.7*(25.2+8.3)=3.7*33.5=123.95

14.8*6.3-6.3*6.5+8.3*3.7=(14.8-6.5)*6.3+8.3*3.7=8.3*6.3+8.3*3.7=8.3*(6.3+3.7)=8.3*10=83

3.7*4*4.3 46.5*4.5 3.7*8.3 46.5*5.5-6.3*6.5=3.7(4*4.3 8.3) 46.5(4.5 5.5)-6.3*6.5=3.7*10.2 46.5*10-6.3*6.5=
