Answer 1

Rút gọn ta có:

\(=\frac{2003}{2004}x\frac{2003}{2005}x\frac{2004}{2005}\)

\(=\frac{2003x2003x2004}{2004x2005x2005}\)

Giản bước ta được: \(\frac{2003x2003}{2005x2005}\)

Answer 2

Ta có : \(\frac{2003}{2004}\)x\(\frac{200320032003}{200520052005}\)x\(\frac{20042004}{20052005}\)

=          \(\frac{2003}{2004}\)x\(\frac{2003x100010001}{2005x100010001}\)x\(\frac{2004x10001}{2005x10001}\)

=           \(\frac{2003x2003x2004}{2004x2005x2005}\)

=             \(\frac{2003x2003}{2005x2005}\)
