\(\frac{2004.2006+1000}{2005.2006-1006}\)

Answer 1

\(\frac{2004.2006+1000}{2005.2006-1006}\)

\(=\frac{2004.2006+1000}{\left(2004+1\right).2006-1006}\)

\(=\frac{2004.2006+1000}{2004.2006+2006-1006}\)

\(=\frac{2004.2006+1000}{2004.2006+1000}\)

\(=1\)

Answer 2

\(\frac{2004x2006+1000}{2005x2006-1006}\)

=\(\frac{1000}{1x2006-1006}\)cùng giảm 2004 lần số 2006

=\(\frac{1000}{1000}=1\)
