k mình nha

Answer 2

\(a=2004.2004=2004.\left(2002+2\right)=2004.2002+2004.2\)

\(b=2002.2006=2002.\left(2004+2\right)=2002.2004+2002.2\)

Vì \(2004.2>2002.2\)

=>\(2004.2002+2004.2>2004.2+2002.2\)

=>\(a>b\)

Answer 3

\(A=\)\(2004.2004=2004.\left(2002+2\right)\)\(2004.2+2004.2002\)

\(B=2002.2006=2002.\left(2004+2\right)=2004.2+200.2\)

vì \(2004.2>2002.2\)

\(=>A>B\)

đ/s: \(A>B\)
