465x2x125x25x5x4x8简便计算

解:465×2×125×25×5×4×8 =465×(2×5)×(125×8)×(25×4) =465×10×1000×100 =4 6500 0000

用简便的方法计算 629x2x125x4x8x25x5 629x2x125x4x8x25x5 =629* (125*8)*(25*4)*(5*2) =629*1000*100*10 =629000000

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...

(125x8)x(25x4)x(5x2)=100000

125x96x25x2x5 =125x8x3x4x25x2x5 =(125x8)x3x(4x25)x(2x5) =1000x3x100x10 =3000000

333x625x125x25x5x16x8x4x2的结果中末尾有10个零

题干不清

125x25x5x128 =125x25x5x2x4x8x2 =(125x8)x(25x4)x(5x2)x2 =1000x100x10x2 =2000000 请采纳。

(125x64)x(25x5)二8000x125二10000000
