25x64x125=25*4*(125*8)*2=100*1000*2=200000
25x64x125=25*8*8*125=(25*4)*2*(8*125)=100*1000*2=100000*2=200000
25*(9x2)x7=(25x8)十(2X10)=1000+20=1020
25x64x125=25*8*8*125=(25*4*2)*(8*125)=200*1000=200000
25x5x64x125=25x5x2*4*8x125=(25*4)*(5*2)*(8*125)=100*10*1000=1000000
125*64*25=125*8*2*4*25=1000*2*100=200000
原式=25x45x125x32=25x45x125x(4x8)=(25x4)x(125x8)x45=100x1000x45=100000=4500000
把96分解为4x6x825X4=1008x125=10006x2x100x1000=1200000 希望采纳
25x125x(4x4x4)=(25x4)x(125x4)x4=100*500*4=200000
25x19x64x125=25x8x8x125x19=200x1000x19=3800x1000=3800000
