〖1/1算式〗
    作业：求算式 (22*0.22)/2*(2/3*0.22)+((38.72+61.60)*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1) 的值.
    题型：数学计算
    解:
          (22*0.22)/2*(2/3*0.22)+((38.72+61.60)*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)
        =4.84/2*(2/3*0.22)+((38.72+61.60)*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)
        =4.84/2*0.146667+((38.72+61.60)*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)
        =4.84/2*0.146667+(100.32*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)
        =4.84/2*0.146667+341.088/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)
        =4.84/2*0.146667+341.088/2*(2/3*3.4*139.04/(38.72+61.60)+1.1)
        =4.84/2*0.146667+341.088/2*(2/3*3.4*139.04/100.32+1.1)
        =4.84/2*0.146667+341.088/2*4.241522
        =2.42*0.146667+341.088/2*4.241522
        =0.354934+341.088/2*4.241522
        =0.354934+170.544*4.241522
        =0.354934+723.366128
        =723.721062
    答案:(22*0.22)/2*(2/3*0.22)+((38.72+61.60)*3.4)/2*(2/3*3.4*(2*38.72+61.60)/(38.72+61.60)+1.1)=723.721062
