√2003-√2002与√2002-√2001谁大?
(注:√为"根号")
(注:√为"根号")
1/（√2003-√2002）=（√2003+√2002）/（√2003-√2002）*（√2003+√2002）=√2003+√2002
1/（√2002-√2001）=（√2002+√2001）/（√2002-√2001）*（√2002+√2001）=√2002+√2001
很明显：（√2003+√2002）>(√2002+√2001)
所以√2003-√2002<√2002-√2001
1/（√2003-√2002）=（√2003+√2002）/（√2003-√2002）*（√2003+√2002）=√2003+√2002
1/（√2002-√2001）=（√2002+√2001）/（√2002-√2001）*（√2002+√2001）=√2002+√2001
很明显：（√2003+√2002）>(√2002+√2001)
所以√2003-√2002<√2002-√2001
1/（√2003-√2002）=（√2003+√2002）/（√2003-√2002）*（√2003+√2002）=√2003+√2002
1/（√2002-√2001）=（√2002+√2001）/（√2002-√2001）*（√2002+√2001）=√2002+√2001 （√2003+√2002）>(√2002+√2001) √2003-√2002<√2002-√2001
√2002-√2001大
后者大
