    作业：求算式 (2228.52*10^3)/(0.91*298*10^2*215)+(0.98*277.39*10^6+1*89.14*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215) 的值.
    题型：数学计算
    解:
          (2228.52*10^3)/(0.91*298*10^2*215)+(0.98*277.39*10^6+1*89.14*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215)
        =2228520/(0.91*298*10^2*215)+(0.98*277.39*10^6+1*89.14*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215)
        =2228520/5830370+(0.98*277.39*10^6+1*89.14*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215)
        =2228520/5830370+360982200/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215)
        =2228520/5830370+360982200/(1.15*4.31×10^6*(1-1782816/(20059.87*10^3))*215)
        =2228520/5830370+360982200/(1.15*4.31×10^6*(1-1782816/20059870)*215)
        =2228520/5830370+360982200/(1.15*4.31×10^6*0.911125*215)
        =2228520/5830370+360982200/970938078.4375
        =0.382226+360982200/970938078.4375
        =0.382226+0.371787
        =0.754013
    答案:(2228.52*10^3)/(0.91*298*10^2*215)+(0.98*277.39*10^6+1*89.14*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^3))*215)=0.754013
