so sanh :
20092010+20092009 va 20102010
so sanh :
20092010+20092009 va 20102010
co cach lam moi tick
20092010+20092009
=20092009.2009+20092009
=20092009(2009+1)
=20092009.2010
Mà 20102010=20102009.2010
nên 20092010+20092009 < 20102010

So sanh 2 phan so
2009×2009+2008/2009×2009+2009 va 2009×2009+2009/2009×2009+2010
So sánh hai phân số :
\(\frac{2009.2009+2008}{2009.2009+2009}\)và \(\frac{2009.2009+2009}{2009.2009+2010}\)

va 4
so sanh
\(\frac{2008}{2009}+\frac{2009}{2010}+\frac{2010}{2011}+\frac{2011}{2008}=1-\frac{1}{2009}+1-\frac{1}{2010}+1-\frac{1}{2011}+1+\frac{3}{2008}\)
\(=4+\left(\frac{1}{2008}-\frac{1}{2009}\right)+\left(\frac{1}{2008}-\frac{1}{2010}\right)+\left(\frac{1}{2008}-\frac{1}{2011}\right)>4\)
