怎么巧算125x73x625x64

125*73*625*64=(125*8)*73*(125*5*8)=1000*73*5000=365000000 125*8=1000

先算125*48=125*40+125*8,再用结果乘以7

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

解答过程: 125×7+125 =125×7+125×1 =125×(7+1) =125×8 =1000

16x75x125 =4*4*75*125 =4*75*4*125 =300*500 =150000

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

提取125×(7+1)=125×8=1000

=125x(7+9)=125x16=125x8x2=1000x2=2000

48×125×7 =6×8×125×7 =(6×7)×(8×125) =42×1000 =42000
