56x25x4x125用简便方法怎么做

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

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

要熟记4*25=100,和8*125=1000. 56*25*4*125=7*8*25*4*125=7*4*25*8*125=7*(4*25)*(8*125)=7*100*1000=700000

= (8*125)*(25*4)=1000*100=100000

原式=7x8x25x4x125=7x(8x125)x(25x4)=7x1000x100=7000x100=700000

56Ⅹ4x125=56Ⅹ(4x125)=56Ⅹ500=28000

56*25*4*125=7x8x25x4x125=7x(8x125)x(25x4)=7x1000x100=700000有不明白的可以追问!谢谢!!祝学习进步!

56*4*125=7*4*(8*125)=28*1000=28000

=(125*4)*(25*4) =500*100 =50000
