A, A=\(\frac{2015^{2015}+1}{2015^{2014}+1}VÀB=\frac{2015^{2014}+1}{2015^{2013}+1}\)
B, B= \(\frac{2010^{2015}+1}{2010^{2016}+1}VÀC=\frac{2010^{2014}+1}{2010^{2015}+1}\)
Tính:
A=(\(\frac{1}{2009}+\frac{1}{2010}+...+\frac{1}{2015}+\frac{1}{2016}\)):(\(\frac{1}{1}-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+...+\frac{1}{2015}-\frac{1}{2016}\))

So sánh : \(A=\frac{2008}{2009}+\frac{2009}{2010}+\frac{2010}{2011}vàB=\frac{2008+2009+2010}{2009+2010+2011}\)
So sánh : \(\frac{1}{1+\frac{2010}{2011}+\frac{2010}{2012}}+\frac{1}{1+\frac{2011}{2010}+\frac{2011}{2012}}+\frac{1}{1+\frac{2012}{2011}+\frac{2012}{2010}}\) và \(\frac{2016}{2017}\)
Tính: A=(1/1009 1/1010 ... 1/2015 1/2010):(1/1-1/2 1/3-1/4 ... 1/2015-1/2016)
-2015. 2009/2010+2015.-1/2010
Tính \(\left(1-\frac{1}{2010}\right)\left(1-\frac{2}{2010}\right)...\left(1-\frac{2016}{2010}\right)\)
