〖1/1算式〗
    作业：求算式 (207.3×10^3)/(0.972×10239.9×215)+(0.85×12.6×10^6)/(1.05×401449×(1-(0.8×207.3)/33161.77)×215) 的值.
    题型：数学计算
    解:
          (207.3×10^3)/(0.972×10239.9×215)+(0.85×12.6×10^6)/(1.05×401449×(1-(0.8×207.3)/33161.77)×215)
        =207300/(0.972×10239.9×215)+(0.85×12.6×10^6)/(1.05×401449×(1-(0.8×207.3)/33161.77)×215)
        =207300/2139934.302+(0.85×12.6×10^6)/(1.05×401449×(1-(0.8×207.3)/33161.77)×215)
        =207300/2139934.302+10710000/(1.05×401449×(1-(0.8×207.3)/33161.77)×215)
        =207300/2139934.302+10710000/(1.05×401449×(1-165.84/33161.77)×215)
        =207300/2139934.302+10710000/(1.05×401449×0.994999×215)
        =207300/2139934.302+10710000/90173885.564235
        =0.096872+10710000/90173885.564235
        =0.096872+0.118771
        =0.215643
    答案:(207.3×10^3)/(0.972×10239.9×215)+(0.85×12.6×10^6)/(1.05×401449×(1-(0.8×207.3)/33161.77)×215)=0.215643
