〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0721/0.05))-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1) 的值.
    题型：数学计算
    解:
          2*500/sqrt(3)*(1+ln(0.0721/0.05))-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1)
        =2*500/sqrt3*(1+ln(0.0721/0.05))-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1)
        =2*500/sqrt3*(1+ln1.442)-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1)
        =2*500/sqrt3*1.366031-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1)
        =2*500/sqrt3*1.366031-350-350*0.05^2/0.0075*((0.1^2/0.0721^2)+1)
        =2*500/sqrt3*1.366031-350-350*0.05^2/0.0075*(1.923665+1)
        =2*500/sqrt3*1.366031-350-350*0.05^2/0.0075*2.923665
        =2*500/1.732051*1.366031-350-350*0.05^2/0.0075*2.923665
        =2*500/1.732051*1.366031-350-350*0.0025/0.0075*2.923665
        =1000/1.732051*1.366031-350-350*0.0025/0.0075*2.923665
        =577.350205*1.366031-350-350*0.0025/0.0075*2.923665
        =788.678278-350-350*0.0025/0.0075*2.923665
        =788.678278-350-0.875/0.0075*2.923665
        =788.678278-350-116.666667*2.923665
        =788.678278-350-341.094251
        =438.678278-341.094251
        =97.584027
    答案:2*500/sqrt(3)*(1+ln(0.0721/0.05))-350-350*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0721^2)+1)=97.584027
