〖1/1算式〗
    作业：求算式 2/sqrt(3)*500*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/sqrt(3)*500*ln(0.0617/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0617^2-1)
        =2/sqrt3*500*ln(0.0617/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0617^2-1)
        =2/sqrt3*500*ln1.234-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0617^2-1)
        =2/sqrt3*500*ln1.234-300+300*0.05^2/0.0075*(0.1^2/0.0617^2-1)
        =2/sqrt3*500*ln1.234-300+300*0.05^2/0.0075*1.626816
        =2/1.732051*500*ln1.234-300+300*0.05^2/0.0075*1.626816
        =2/1.732051*500*0.210261-300+300*0.05^2/0.0075*1.626816
        =2/1.732051*500*0.210261-300+300*0.0025/0.0075*1.626816
        =1.1547*500*0.210261-300+300*0.0025/0.0075*1.626816
        =577.35*0.210261-300+300*0.0025/0.0075*1.626816
        =121.394188-300+300*0.0025/0.0075*1.626816
        =121.394188-300+0.75/0.0075*1.626816
        =121.394188-300+100*1.626816
        =121.394188-300+162.6816
        =-178.605812+162.6816
        =-15.924212
    答案:2/sqrt(3)*500*ln(0.0617/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0617^2-1)=-15.924212
