20042004x2006/20062006x2000

=10001x2004x2006/10001x2006x2000

=2004/2000=501/500

=55/32 chia cho 32/56+

=55/32x33/56

BUON QUA CO BAN NAO BIET LAM KO?

\(\left(\frac{20052005}{20062006}-\frac{20042004}{20052005}\right)\cdot2005\cdot2006\)

=\(\left(\frac{2005\cdot10001}{2006\cdot10001}-\frac{2004\cdot10001}{2005\cdot10001}\right)\cdot2005\cdot2006\)

=\(\frac{2005\cdot2005\cdot2006}{2006}-\frac{2004\cdot2005\cdot2006}{2005}\)

= \(2005\cdot2005-2004\cdot2006\)

=\(2005^2-\left(2005-1\right)\cdot\left(2005+1\right)\)

=\(2005^2-2005^2+1\)

=1

1003/1002

Ta có:

\(\frac{20062006}{20042004}\)

Rút gọn: \(\frac{20062006}{20042004}=\frac{2006}{2004}=\frac{1003}{1002}\)

1 nha bạn k mk nha

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 :)
