125x25x4x8的简便计算

[(4x8)x25-8]x125=4*8*25*125-8*125=4*25*8*125-8*125=100*1000-1000=100000-1000=99000

125x7x25x4x8=7x(125x8)x(25x4)=7x1000x100=700000希望能帮到你!

224x25x125x4x8=224x(25x4)x(125x8)=224x100x1000=22400000

125x25x4x8=(125x2)x4x(25x4)=250x4x100=1000x100=100000

原式=(4x25)x(8x125)=100x1000=100000

125X4X25X8=(125*8)*(4*25)=1000*100=100000

125x25x8x4x2x8=125x8x25x4x2x8=1000x100x16=1600000

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

432x2x125x25x5x4x8=432*2*5*125*8*25*4=4320*1000*100=4320*100000=432000000

4x8x25x125=4*25*(125*8)=100*1000=100000
