〖1/1算式〗
    作业：求算式 2/sqrt(3)*500*ln(0.0674/0.05)-330+330*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0674^2-1) 的值.
    题型：数学计算
    解:
          2/sqrt(3)*500*ln(0.0674/0.05)-330+330*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0674^2-1)
        =2/sqrt3*500*ln(0.0674/0.05)-330+330*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0674^2-1)
        =2/sqrt3*500*ln1.348-330+330*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0674^2-1)
        =2/sqrt3*500*ln1.348-330+330*0.05^2/0.0075*(0.1^2/0.0674^2-1)
        =2/sqrt3*500*ln1.348-330+330*0.05^2/0.0075*1.201305
        =2/1.732051*500*ln1.348-330+330*0.05^2/0.0075*1.201305
        =2/1.732051*500*0.298622-330+330*0.05^2/0.0075*1.201305
        =2/1.732051*500*0.298622-330+330*0.0025/0.0075*1.201305
        =1.1547*500*0.298622-330+330*0.0025/0.0075*1.201305
        =577.35*0.298622-330+330*0.0025/0.0075*1.201305
        =172.409412-330+330*0.0025/0.0075*1.201305
        =172.409412-330+0.825/0.0075*1.201305
        =172.409412-330+110*1.201305
        =172.409412-330+132.14355
        =-157.590588+132.14355
        =-25.447038
    答案:2/sqrt(3)*500*ln(0.0674/0.05)-330+330*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0674^2-1)=-25.447038
