\(\dfrac{2000}{2001}\cdot\dfrac{2002}{2003}\cdot\dfrac{2001}{2002}\cdot\dfrac{2003}{2004}\cdot\dfrac{2006}{2000}=\dfrac{2006}{2004}=\dfrac{1003}{1002}\)
Cho A =2002/2001+2003/2002+2004/2003+2005/2004+2006/2005+2007/2006+2008/20007+2009/20008.So sánh A với 8
Cho A = \(\frac{2000}{2001}+\frac{2001}{2002}+\frac{2002}{2003}+\frac{2003}{2004}+\frac{2005}{2006}+\frac{2006}{2007}+\frac{2007}{2008}+\frac{2008}{2009}+\frac{2009}{2010}+\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}+\frac{2013}{2014}+\frac{2014}{2015}+\frac{2015}{2016}\)
Hãy so sánh tổng các phân số trong A và so sánh với 15.
Cho A=2002/2001+2003/2002+2004/2003+2005/2004+2006/2005+2007/2006+2008/2007+2009/2008
Hãy so sánh A với 8 và giải thích tại sao
A=2001/ 2002+2002/2003+2003/2004+....+2015/2016. Hãy so sánh tổng A với 15
