〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+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*500/sqrt(3)*(1+ln(0.0674/0.05))-330-330*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0674^2)+1)
        =2*500/sqrt3*(1+ln(0.0674/0.05))-330-330*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0674^2)+1)
        =2*500/sqrt3*(1+ln1.348)-330-330*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0674^2)+1)
        =2*500/sqrt3*1.298622-330-330*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0674^2)+1)
        =2*500/sqrt3*1.298622-330-330*0.05^2/0.0075*((0.1^2/0.0674^2)+1)
        =2*500/sqrt3*1.298622-330-330*0.05^2/0.0075*(2.201305+1)
        =2*500/sqrt3*1.298622-330-330*0.05^2/0.0075*3.201305
        =2*500/1.732051*1.298622-330-330*0.05^2/0.0075*3.201305
        =2*500/1.732051*1.298622-330-330*0.0025/0.0075*3.201305
        =1000/1.732051*1.298622-330-330*0.0025/0.0075*3.201305
        =577.350205*1.298622-330-330*0.0025/0.0075*3.201305
        =749.759678-330-330*0.0025/0.0075*3.201305
        =749.759678-330-0.825/0.0075*3.201305
        =749.759678-330-110*3.201305
        =749.759678-330-352.14355
        =419.759678-352.14355
        =67.616128
    答案:2*500/sqrt(3)*(1+ln(0.0674/0.05))-330-330*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0674^2)+1)=67.616128
