32x4x25x3用简便运算

原式=25*4*25*4*2=10000*2=20000.

32X25X25=25X25X4X4X2=(25X4)X(25X4)X2=100X100X2=10000X2=20000

4x31x25x3=(4x25)x(31x3)=100x93=9300请好评如果你认可我的回答,敬请及时采纳,~如果你认可我的回答,请及时点击【采纳为满意回答】按钮~~手机提问的朋友在客户端右上角评价点【满意】即可.~你的采纳是我前进的动力~~O(∩_∩)O,记得好评和采纳,互相帮助

32x25x4=32x100=3200

原式 =33x(25x4) =33x100 =3300 供参考.

很简单啊!=125*8*4*4*25=(1000*4)*(4*25)=4000*100=4000000

32x25x1245=4x25x4x2x1245=100x4x2490=400x(2500-10)=1000000-4000=996000

=8x4x25x7=(8x7)x(4x25)==56x100=5600

32X25X7=25X4X8X7=(25X4)X(8X7)=100X56=5600

75x4x25x3=(75*3)*(4*25)=225*100=22500
