125x64x25=125x8x8x25=1000x200=200000
125x25x64=125*25*8*8=125*8*25*8=1000*25*4*2=1000*100*2=200000
5x125x64x25=5*125*8*4*2*25=(5*2)*(125*8)*(4*25)=10*1000*100=1000000
125x25x64=125*8 *25*4*2=1000*100*2=200000
125*64 =125*8*8 =1000*8 =8000. 请点击右下角的 [采纳答案] 谢谢.
125*8*25*4*2
125x25x64 =125x25x(8x4x2) =125x8x(25x4)x2 =1000x100x2 =200000
=125*25*(8*4*2)=(125*8)*(25*4)*2=1000*100*2=200000
125x25x64=125x8x25x4x2=1000x100x2=200000
