Question

Cho

\(A=\frac{10^{2004}+1}{10^{2005}+1}\)

\(B=\frac{10^{2005}+1}{10^{2006}+1}\)

So sánh A và B

Answer 1

Ta có:10A=\(\frac{10^{2005}+10}{10^{2005}+1}\)=1+\(\frac{9}{10^{2005}+1}\)

          10B=\(\frac{10^{2006}+10}{10^{2006}+1}\) =1+\(\frac{9}{10^{2006}+1}\) 

Mà:\(\frac{9}{10^{2005}+1}\) >\(\frac{9}{10^{2006}+1}\) 

Vậy:1+\(\frac{9}{10^{2005}+1}\) >1+\(\frac{9}{10^{2006}+1}\)

Vậy:A>B
