Question

So sánh phân số :

2^2014+1/2^2014 và 2^2014+2/2^2014+1

 

 

Answer 1

\(\frac{2^{2014}+2}{2^{2014}+1}=\frac{2^{2014}+1+1}{2^{2014}+1}=1+\frac{1}{2^{2014}+1}\)

\(\frac{2^{2014}+1}{2^{2014}}=1+\frac{1}{2^{2014}}\)

Do \(2^{2014}+1>2^{2014}\Rightarrow\frac{1}{2^{2014}+1}<\frac{1}{2^{2014}}\Rightarrow1+\frac{1}{2^{2014}+1}<1+\frac{1}{2^{2014}}\Rightarrow\frac{2^{2014}+2}{2^{2014}+1}<\frac{2^{2014}+1}{2^{2014}}\)
