Giải nhanh giùm mik nhé!

Answer 1

\(\frac{2007x2010-1007}{2008x2009-1009}\)

\(=\frac{2007x2009+\left(2007-1007\right)}{2007x2009+\left(2009-1009\right)}\)

\(=\frac{2007x2009+1000}{2007x2009+1000}\)

=1

Answer 2

\(\frac{2007x2010-1007}{2008x2009-1009}\)

=\(\frac{2007x2009-\left(2007-1007\right)}{2007x2009-\left(2009-1009\right)}\)

= \(\frac{2007x2009-1000}{2007x2009-1000}\)

= 1
