20062006. 2004- 20042004. 2006

= 2006. 10001. 2004- 2004. 10001. 2006

= 0

20062006 . (2004 -2006 )

= 200620 . (-2)

= -40124012

\(\frac{2006\times2006\times20052005-2005\times2005\times20062006}{2005\times20042004}\)

\(=\frac{2006\times2006\times2005\times10001-2005\times2005\times2006\times10001}{2005\times2004\times10001}\)

\(=\frac{2006\times10001\times2005}{2005\times2004\times10001}=\frac{1003}{1002}\)

Ta có:

a,1313/1515=101.13/101.15=13/13.

b,123123/127127=1001.123/1001.127
