〖1/1算式〗
作业：求算式 (309.6×10^3)/(0.89×13280×215)+(1.0×21.4×10^6)/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215) 的值.
题型：数学计算
解:
(309.6×10^3)/(0.89×13280×215)+(1.0×21.4×10^6)/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215)
=309600/(0.89×13280×215)+(1.0×21.4×10^6)/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215)
=309600/2541128+(1.0×21.4×10^6)/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215)
=309600/2541128+21400000/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215)
=309600/2541128+21400000/(1.05×1978146×(1-247680/7321755.6)×215)
=309600/2541128+21400000/(1.05×1978146×0.966172×215)
=309600/2541128+21400000/431460009.30812
=0.121836+21400000/431460009.30812
=0.121836+0.049599
=0.171435
答案:(309.6×10^3)/(0.89×13280×215)+(1.0×21.4×10^6)/(1.05×1978146×(1-(0.8×309.6×10^3)/7321755.6)×215)=0.171435
