465x2x125x25x5x4x8简便计算

125*8*25*4*50*2*40*5

10个0,因为999乘以其他数字不可能出现末尾0,所以排除。625×125×25×5×16×8×4×2可以化简为5×125(由625变式而出)×125×25×5×8×2(由16变成)×8×8(由4×2得出 ). 然后得出125×8× 125×8× 25×5×8 ×5×2 ×5 1000× 1000 × 1000 ×10 × 5 所以最后末尾是...

125x25x256x5 =125×25×2×8×4×4×5 =125*8×25*4×2*5×4 =1000×100×10×4 =4000000

125*25*5*64 =125*5*5*5*64 =15000*60+15000*4 =900000+60000 =960000 求采纳

=(125x8)5x(4x25)=1000×5×100=500000

65x37x125-37x25x54=37x(25x65x5-25x54)=37x25x(65x5-54)=37x25x(325-54)=37x25x271=250675

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