Answer 1

khó wá ko giải đc 

Answer 2

=1/2x2/3x/3/4/.................x2003/2004

= 1x2x3x................x2003

    ___________________

2x3x4x................x 2004

=1/2004

Answer 3

(1 - 1/2) . (1 - 1/3 ). (1- 1/4) . (1- 1/5).  ....  . (1- 1/2004)

\(=\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\cdot...\cdot\frac{2003}{2004}\)

\(=\frac{1\cdot\left(2\cdot3\cdot4\cdot...\cdot2003\right)}{\left(2\cdot3\cdot4\cdot5\cdot....\cdot2003\right)\cdot2004}\)

\(=\frac{1}{2004}\)

Answer 4

= \(\frac{2-1}{2}\). \(\frac{3-1}{3}\). \(\frac{4-1}{4}\). ............... . \(\frac{2003-1}{2003}\). \(\frac{2004-1}{2004}\)

= \(\frac{1}{2}\). \(\frac{2}{3}\). \(\frac{3}{4}\). ................... . \(\frac{2002}{2003}\). \(\frac{2003}{2004}\)

= \(\frac{1}{2004}\)

mk nha
