Giải ra nha các bạn

Lời giải đó

$\left(\frac{20052005}{20062006}-\frac{20042004}{20052005}\right)\cdot 2005\cdot 2006$

=$\left(\frac{2005\cdot 10001}{2006\cdot 10001}-\frac{2004\cdot 10001}{2005\cdot 10001}\right)\cdot 2005\cdot 2006$

=$\frac{2005\cdot 2005\cdot 2006}{2006}-\frac{2004\cdot 2005\cdot 2006}{2005}$

= $2005\cdot 2005-2004\cdot 2006$

=${}^{}-\left(2005-1\right)\cdot \left(2005+1\right)$

=${}^{}-{}^{}+1$

=1

(20052005/20062006-20042004/20052005)x2005/2006

=(2005x10001/2006x10001-2004x10001/2005x10001)x2005/2006

=(2005/2006-2004/2005)x2005/2006

=((2005x2005-2004x2006)/2006x2005)x2005/2006

=((2004x2005+2005-2004x2005+2004)/2005x2006)x2005/2006

=(1/2005x2006)x2005/2006

=2005/2005x2006x2006

=1/2006x2006=1/4024036

chúc bạn học tốt nha :)

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.
