So sánh : \(A=\frac{2008}{2009}+\frac{2009}{2010}+\frac{2010}{2011}vàB=\frac{2008+2009+2010}{2009+2010+2011}\)
So sánh : A=\(\frac{2008}{2009}\)+\(\frac{2009}{2010}\)+\(\frac{2010}{2011}\)và B=\(\frac{2008+2009+2010}{2009+2010+2011}\)
So sánh A và B biết
A=\(\frac{2009}{2010}+\frac{2010}{2011}+\frac{2011}{2012}\)
B=\(\frac{2009+2010+2011}{2010+2011+2012}\)
So sánh:
A=\(\frac{2009^{2009}+1}{2009^{2010}+1}\)và B=\(\frac{2009^{2010}-2}{2009^{2011}-2}\)
so sánh A=\(\frac{2009^{2009}+1}{2009^{2010}+1}\)B=\(\frac{2009^{2010}-2}{2009^{2011}-2}\)
so sánh \(\frac{-22}{45}\)và\(\frac{-51}{103}\)
so sánh \(\frac{2009^{2009}+1}{2009^{2010}+1}\)và\(\frac{2009^{2010}-2}{2009^{2011}-2}\)
A=\(\frac{2009^{2009}+1}{2009^{2010}+1}\)
B=\(\frac{2009^{2010}-2}{2009^{2011}-2}\)
