〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0617/0.05))-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1) 的值.
    题型：数学计算
    解:
          2*500/sqrt(3)*(1+ln(0.0617/0.05))-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1)
        =2*500/sqrt3*(1+ln(0.0617/0.05))-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1)
        =2*500/sqrt3*(1+ln1.234)-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1)
        =2*500/sqrt3*1.210261-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1)
        =2*500/sqrt3*1.210261-300-300*0.05^2/0.0075*((0.1^2/0.0617^2)+1)
        =2*500/sqrt3*1.210261-300-300*0.05^2/0.0075*(2.626816+1)
        =2*500/sqrt3*1.210261-300-300*0.05^2/0.0075*3.626816
        =2*500/1.732051*1.210261-300-300*0.05^2/0.0075*3.626816
        =2*500/1.732051*1.210261-300-300*0.0025/0.0075*3.626816
        =1000/1.732051*1.210261-300-300*0.0025/0.0075*3.626816
        =577.350205*1.210261-300-300*0.0025/0.0075*3.626816
        =698.744436-300-300*0.0025/0.0075*3.626816
        =698.744436-300-0.75/0.0075*3.626816
        =698.744436-300-100*3.626816
        =698.744436-300-362.6816
        =398.744436-362.6816
        =36.062836
    答案:2*500/sqrt(3)*(1+ln(0.0617/0.05))-300-300*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0617^2)+1)=36.062836
