〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0635/0.05))-310-310*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*500/sqrt(3)*(1+ln(0.0635/0.05))-310-310*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0635^2)+1)
        =2*500/sqrt3*(1+ln(0.0635/0.05))-310-310*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0635^2)+1)
        =2*500/sqrt3*(1+ln1.27)-310-310*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0635^2)+1)
        =2*500/sqrt3*1.239017-310-310*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0635^2)+1)
        =2*500/sqrt3*1.239017-310-310*0.05^2/0.0075*((0.1^2/0.0635^2)+1)
        =2*500/sqrt3*1.239017-310-310*0.05^2/0.0075*(2.480005+1)
        =2*500/sqrt3*1.239017-310-310*0.05^2/0.0075*3.480005
        =2*500/1.732051*1.239017-310-310*0.05^2/0.0075*3.480005
        =2*500/1.732051*1.239017-310-310*0.0025/0.0075*3.480005
        =1000/1.732051*1.239017-310-310*0.0025/0.0075*3.480005
        =577.350205*1.239017-310-310*0.0025/0.0075*3.480005
        =715.346719-310-310*0.0025/0.0075*3.480005
        =715.346719-310-0.775/0.0075*3.480005
        =715.346719-310-103.333333*3.480005
        =715.346719-310-359.600516
        =405.346719-359.600516
        =45.746203
    答案:2*500/sqrt(3)*(1+ln(0.0635/0.05))-310-310*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0635^2)+1)=45.746203
