5x125x64x25怎么简算

5x125x64x25=5*125*8*4*2*25=(5*2)*(125*8)*(4*25)=10*1000*100=1000000

125x64x25=125x8x8x25=1000x200=200000

125x25x64=125*8 *25*4*2=1000*100*2=200000

因为 2*4*25=1008*125=100064=2*4*85x15x25x125x64=5x15x25x125x2*4*8=(5*2)*(25*4)* (125*8)*15=10*100*1000*15=15000000

解:原式=125x25x(8x4x2)x5=(125x8)x(25x4)x(2x5)=1000x100x10=1000000

125x25x64=125*25*8*8=125*8*25*8=1000*25*4*2=1000*100*2=200000

5x64x25x125=5*2*(4*25)*(8*125)=10*100*1000=1000000

125*8*8*25=1000X200=200000

125x25x64x5=125x25x8x4x2x5=(125x8)x(25x4)x(2x5)=1000x100x10=1000000

125x64x25x5=(125x8)x(4x25)x(5x2)=1000x100x10=1000000
