作业:求算式 (2228.52*10^3)/(0.91*298*10^2*215)+(0.98*277.39*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*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)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*215)
=2228520/(0.91*298*10^2*215)+(0.98*277.39*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*215)
=2228520/5830370+(0.98*277.39*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*215)
=2228520/5830370+271842200/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*215)
=2228520/5830370+271842200/(1.15*4.31×10^6*(1-1782816/(20059.87*10^2))*215)
=2228520/5830370+271842200/(1.15*4.31×10^6*(1-1782816/2005987)*215)
=2228520/5830370+271842200/(1.15*4.31×10^6*0.111252*215)
=2228520/5830370+271842200/118555415.67
=0.382226+271842200/118555415.67
=0.382226+2.292955
=2.675181 答案:(2228.52*10^3)/(0.91*298*10^2*215)+(0.98*277.39*10^6)/(1.15*4.31×10^6*(1-(0.8*2228.52*10^3)/(20059.87*10^2))*215)=2.675181你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
