〖1/1算式〗
作业：求算式 (157.5×10^3)/(0.921×2548.52×305)+(0.27×1.2×10^6)/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305) 的值.
题型：数学计算
解:
(157.5×10^3)/(0.921×2548.52×305)+(0.27×1.2×10^6)/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305)
=157500/(0.921×2548.52×305)+(0.27×1.2×10^6)/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305)
=157500/715892.0106+(0.27×1.2×10^6)/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305)
=157500/715892.0106+324000/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305)
=157500/715892.0106+324000/(1.0×93974.09×(1-126000/1298105.31)×305)
=157500/715892.0106+324000/(1.0×93974.09×0.902935×305)
=157500/715892.0106+324000/25880010.96097
=0.220005+324000/25880010.96097
=0.220005+0.012519
=0.232524
答案:(157.5×10^3)/(0.921×2548.52×305)+(0.27×1.2×10^6)/(1.0×93974.09×(1-(0.8×157.5×10^3)/1298105.31)×305)=0.232524
