〖1/1算式〗
    作业：求算式 (442.9×10^3)/(0.994×7916.8×215)+(0.85×14.7×10^6)/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215) 的值.
    题型：数学计算
    解:
          (442.9×10^3)/(0.994×7916.8×215)+(0.85×14.7×10^6)/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215)
        =442900/(0.994×7916.8×215)+(0.85×14.7×10^6)/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215)
        =442900/1691899.328+(0.85×14.7×10^6)/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215)
        =442900/1691899.328+12495000/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215)
        =442900/1691899.328+12495000/(1.15×819724.71×(1-354.32/157459.87)×215)
        =442900/1691899.328+12495000/(1.15×819724.71×0.99775×215)
        =442900/1691899.328+12495000/202220911.444795
        =0.261777+12495000/202220911.444795
        =0.261777+0.061789
        =0.323566
    答案:(442.9×10^3)/(0.994×7916.8×215)+(0.85×14.7×10^6)/(1.15×819724.71×(1-(0.8×442.9)/157459.87)×215)=0.323566
