〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0696/0.05))-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1) 的值.
    题型：数学计算
    解:
          2*500/sqrt(3)*(1+ln(0.0696/0.05))-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1)
        =2*500/sqrt3*(1+ln(0.0696/0.05))-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1)
        =2*500/sqrt3*(1+ln1.392)-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1)
        =2*500/sqrt3*1.330742-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1)
        =2*500/sqrt3*1.330742-340-340*0.05^2/0.0075*((0.1^2/0.0696^2)+1)
        =2*500/sqrt3*1.330742-340-340*0.05^2/0.0075*(2.064341+1)
        =2*500/sqrt3*1.330742-340-340*0.05^2/0.0075*3.064341
        =2*500/1.732051*1.330742-340-340*0.05^2/0.0075*3.064341
        =2*500/1.732051*1.330742-340-340*0.0025/0.0075*3.064341
        =1000/1.732051*1.330742-340-340*0.0025/0.0075*3.064341
        =577.350205*1.330742-340-340*0.0025/0.0075*3.064341
        =768.304167-340-340*0.0025/0.0075*3.064341
        =768.304167-340-0.85/0.0075*3.064341
        =768.304167-340-113.333333*3.064341
        =768.304167-340-347.291979
        =428.304167-347.291979
        =81.012188
    答案:2*500/sqrt(3)*(1+ln(0.0696/0.05))-340-340*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0696^2)+1)=81.012188
