〖1/1算式〗
    作业：求算式 2/sqrt(3)*500*ln(0.0635/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0635^2-1) 的值.
    题型：数学计算
    解:
          2/sqrt(3)*500*ln(0.0635/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0635^2-1)
        =2/sqrt3*500*ln(0.0635/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0635^2-1)
        =2/sqrt3*500*ln1.27-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0635^2-1)
        =2/sqrt3*500*ln1.27-300+300*0.05^2/0.0075*(0.1^2/0.0635^2-1)
        =2/sqrt3*500*ln1.27-300+300*0.05^2/0.0075*1.480005
        =2/1.732051*500*ln1.27-300+300*0.05^2/0.0075*1.480005
        =2/1.732051*500*0.239017-300+300*0.05^2/0.0075*1.480005
        =2/1.732051*500*0.239017-300+300*0.0025/0.0075*1.480005
        =1.1547*500*0.239017-300+300*0.0025/0.0075*1.480005
        =577.35*0.239017-300+300*0.0025/0.0075*1.480005
        =137.996465-300+300*0.0025/0.0075*1.480005
        =137.996465-300+0.75/0.0075*1.480005
        =137.996465-300+100*1.480005
        =137.996465-300+148.0005
        =-162.003535+148.0005
        =-14.003035
    答案:2/sqrt(3)*500*ln(0.0635/0.05)-300+300*0.05^2/(0.1^2-0.05^2)*(0.1^2/0.0635^2-1)=-14.003035
