4x16x25x5 125的简算

16x25x5x125=(2X8)X25X5X125=(125X8)X25X(2X5)=1000X25X10=250000希望对你有帮助,满意请及时采纳,你的采纳是我回答的动力!

5x25x96x125的简便算法=5x25x(4x8x3)x125=(25x4)(125x8)(5x3)=100x1000x15=1500000

16X25X5X125用简便方法算16X25X5X125=25*(125*16*5)=25*(125*80)=25*10000=250000

16x25x125=4x4x25x125=4x25x4x125=(4x25)x(4x125)=100x500=50000

4*16*25*5*125=(4*25)*(16*5*125)=100*10000=1000000

=(4乘以5)乘以(16乘以25)乘以125 =20乘以400乘以125 =8000乘以125 =1000000

原式=(4x4)x(2x8)x25x125=(4x25)x(8x125)x(4x2)=100x1000x8=100000x8=800000

125x25x16=125*25*4*4=125*4+25*4=600*100=60000

56x5x125用简便方法计算怎么做?56x5x125=7*8*125*5=7*1000*5=35000

56x25x4x125=7x8x125x25x4=7x(8x125)x(25x4)=7x1000x100=700000 希望帮到你 望采纳 谢谢 加油
