〖1/1算式〗
作业:求算式 80/(1+10%)/950.25+80/(1+10%)^2/950.25+1080/(1+10%)^3/950.25 的值.
题型:数学计算
解:
80/(1+10%)/950.25+80/(1+10%)^2/950.25+1080/(1+10%)^3/950.25
=80/1.1/950.25+80/(1+10%)^2/950.25+1080/(1+10%)^3/950.25
=80/1.1/950.25+80/1.1^2/950.25+1080/(1+10%)^3/950.25
=80/1.1/950.25+80/1.1^2/950.25+1080/1.1^3/950.25
=80/1.1/950.25+80/1.21/950.25+1080/1.1^3/950.25
=80/1.1/950.25+80/1.21/950.25+1080/1.331/950.25
=72.727273/950.25+80/1.21/950.25+1080/1.331/950.25
=0.076535+80/1.21/950.25+1080/1.331/950.25
=0.076535+66.115702/950.25+1080/1.331/950.25
=0.076535+0.069577+1080/1.331/950.25
=0.076535+0.069577+811.419985/950.25
=0.076535+0.069577+0.853902
=0.146112+0.853902
=1.000014 答案:80/(1+10%)/950.25+80/(1+10%)^2/950.25+1080/(1+10%)^3/950.25=1.000014你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
