So sánh A vs B
\(A=\frac{2008^{2008}+1}{2008^{2009}+1}\)
\(B=\frac{2008^{2007}+1}{2008^{2008}+1}\)
So sánh: A=2008^2008+1/2008^2009+1 và B = 2008^2007+1/2008^2008+1
So sánh bt: \(A=\dfrac{2008^{2008}+1}{2008^{2009}+1};B=\dfrac{2008^{2007}+1}{2008^{2008}+1}\)
So sánh A và B biết \(A=\frac{2006}{2007}-\frac{2007}{2008}+\frac{2008}{2009}-\frac{2009}{2010};B=\frac{1}{2006.2007}-\frac{1}{2008.2009}\)

Bài 2:Tính tỉ số \(\frac{A}{B}\), biết:
\(A=\frac{1}{2}\)+\(\frac{1}{3}+\frac{1}{4}+....+\frac{1}{2007}+\frac{1}{2008}+\frac{1}{2009}\)
\(B=\frac{2008}{1}+\frac{2007}{2}+\frac{2006}{3}+...+\frac{2}{2007}+\frac{1}{2008}\)
So sánh hai số sau:
\(A=\frac{1}{2006}\)
\(B=\frac{1}{2008}+\left(\frac{1}{2008}+\frac{1}{2008^2}\right)^2+...+\left(\frac{1}{2008}+\frac{1}{2008^2}+...+\frac{1}{2008^{2007}}\right)^{2007}\)
So sánh hai số sau:
\(A=\frac{1}{2006}\)
\(B=\frac{1}{2008}+\left(\frac{1}{2008}+\frac{1}{2008^2}\right)^2+...+\left(\frac{1}{2008}+\frac{1}{2008^2}+...+\frac{1}{2008^{2007}}\right)^{2007}\)
so sánh:
A= 20082008+1/20082009+1
B=20082007+1/20082008+1
so sánh 2008^2008+1 / 2008^2009+1 và 2008^2007+1 / 2008^2008+1
