    作业：求算式 0.78549551-0.0097903096*(ln(12.140836))^2-0.39657121/(312.140836)*ln(12.140836) 的值.
    题型：数学计算
    解:
          0.78549551-0.0097903096*(ln(12.140836))^2-0.39657121/(312.140836)*ln(12.140836)
        =0.78549551-0.0097903096*(ln12.140836)^2-0.39657121/(312.140836)*ln(12.140836)
        =0.78549551-0.0097903096*2.496575^2-0.39657121/(312.140836)*ln(12.140836)
        =0.78549551-0.0097903096*2.496575^2-0.39657121/312.140836*ln(12.140836)
        =0.78549551-0.0097903096*2.496575^2-0.39657121/312.140836*ln12.140836
        =0.78549551-0.0097903096*2.496575^2-0.39657121/312.140836*2.496575
        =0.78549551-0.0097903096*6.232886730625-0.39657121/312.140836*2.496575
        =0.78549551-0.061022-0.39657121/312.140836*2.496575
        =0.78549551-0.061022-0.00127*2.496575
        =0.78549551-0.061022-0.003171
        =0.724474-0.003171
        =0.721303
    答案:0.78549551-0.0097903096*(ln(12.140836))^2-0.39657121/(312.140836)*ln(12.140836)=0.721303
