A=\(\frac{2009.2010-2}{2008+2008.2010}=\frac{\left(2008+1\right).2010-2}{2008+2008.2010}\)
\(=\frac{2008.2010+2010-2}{2008+2008.2010}\)
\(=\frac{2008.2010+2008}{2008+2008.2010}=1\)
B=\(\frac{-2009.20102010}{20092009.2010}=\frac{-2009.2010.10001}{2009.10001.2010}=-1\)
Vậy A+|B= 1+(-1)=0
Cho \(A=\frac{2009.2010-2}{2008+2008.2010};B=\frac{-2009.20102010}{20092009.2010}\). Tính A + B
Cho A = \(\frac{2009.2010-2}{2008+2008.2010}\) và B = \(\frac{-2009.20102010}{20092009.2010}\)
Tính A + B
Cho A=\(\frac{2009.2010-2}{2008+2008.2010}\); B=\(\frac{-2009.20102010}{20092009.2010}\)
Tính A+B
Cho A= \(\frac{2009.2010-2}{2008+2008.2010}\)
B= \(\frac{-2009.20102010}{20092009.2010}\)
Tính A+B
\(A=\frac{2009.2010-2}{2008+2008.2010}\)
\(B=\frac{-2009.20102010}{20092009.2010}\)
So sánh A và B
Rút gọn:
A=2009.2010-2/2008+2008.2010 và B= -2009.20102010/20092009.2010
tinh gia tri :
A = \(\frac{2009.2010-2}{2008+2008.2010}\) ; B = \(\frac{-2009.20102010}{20092009.2010}\)
Rút gọn E=\(\frac{2009.2010-2}{2008+2008.2010}\)+\(\frac{-2009.20102010}{20092009.2010}\)
\(y=\frac{2010.2009-2}{2008+2008.2010}+\frac{-2009.20102010}{20092009.2010}\)
