〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0654/0.05))-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1) 的值.
    题型：数学计算
    解:
          2*500/sqrt(3)*(1+ln(0.0654/0.05))-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1)
        =2*500/sqrt3*(1+ln(0.0654/0.05))-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1)
        =2*500/sqrt3*(1+ln1.308)-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1)
        =2*500/sqrt3*1.268499-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1)
        =2*500/sqrt3*1.268499-320-320*0.05^2/0.0075*((0.1^2/0.0654^2)+1)
        =2*500/sqrt3*1.268499-320-320*0.05^2/0.0075*(2.338+1)
        =2*500/sqrt3*1.268499-320-320*0.05^2/0.0075*3.338
        =2*500/1.732051*1.268499-320-320*0.05^2/0.0075*3.338
        =2*500/1.732051*1.268499-320-320*0.0025/0.0075*3.338
        =1000/1.732051*1.268499-320-320*0.0025/0.0075*3.338
        =577.350205*1.268499-320-320*0.0025/0.0075*3.338
        =732.368158-320-320*0.0025/0.0075*3.338
        =732.368158-320-0.8/0.0075*3.338
        =732.368158-320-106.666667*3.338
        =732.368158-320-356.053334
        =412.368158-356.053334
        =56.314824
    答案:2*500/sqrt(3)*(1+ln(0.0654/0.05))-320-320*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0654^2)+1)=56.314824
