怎么巧算125x73x625x64

64=8x8 125x8=1000 625x8=5000 125x73x625x64=(125x8)x(625x8)x73=365000000

请采纳,谢谢

125*7 =125*(8-1) =125*8-125 =1000-125 =875

解:125×76×2×4 =125×2×4×76 =(125×2×4)×76 =1000×76 =76000

=0.111×8×125×73+111×9×3 =0.111×(8×125)×73+111×(9×3) =111×73+111×27 =111×(73+27) =111×100 =11100

125x456÷7.89÷4.56x78.9÷1.25 =(125÷1.25)x(456÷4.56)x(78.9÷7.89) =100×100×10 =10000

你好,很高兴为你解答 0.888x125X73+999×3简便计算 =0.111x8x125x73+111x27 =111x73+111x27 =111x(73+27) =11100 满意采纳哦!
