〖1/1算式〗
    作业：求算式 (1.989*(2*43.073+13.396*1.989+8.54217))/(3*(43.073+13.396*1.989+8.54217)) 的值.
    题型：数学计算
    解:
          (1.989*(2*43.073+13.396*1.989+8.54217))/(3*(43.073+13.396*1.989+8.54217))
        =(1.989*121.332814)/(3*(43.073+13.396*1.989+8.54217))
        =241.330967/(3*(43.073+13.396*1.989+8.54217))
        =241.330967/(3*78.259814)
        =241.330967/234.779442
        =1.027905
    答案:(1.989*(2*43.073+13.396*1.989+8.54217))/(3*(43.073+13.396*1.989+8.54217))=1.027905
