\(\frac{2010.2011-1005}{2010.2010+1005}\)= \(\frac{2010.\left(2010+1\right)-1005}{2010.2010+1005}\)= \(\frac{2010.2010+2010-1005}{2010.2010+1005}\)= \(\frac{2010.2010+1005}{2010.2010+1005}\)=1
2010 . 2011 - \(\frac{1005}{2010}\).2010 + 1005
= 4042110 - 1 + 1005
4043114

đề như zày phải k bạn\(\frac{2010\cdot2011-1005}{2010\cdot2010+1005}\)
