1012 nhé bạn

diễn giải dùm mik đc k?

2000/2001 * 2002/2003 * 2001/2002 * 2003/2004*2006/2000
=((2000/2001).2002):2003.2001/2002).2003):2004.2006)/2000
=1.000998004

\(\dfrac{2000}{2001}\cdot\dfrac{2002}{2003}\cdot\dfrac{2001}{2002}\cdot\dfrac{2003}{2004}\cdot\dfrac{2006}{2000}=\dfrac{2006}{2004}=\dfrac{1003}{1002}\)

(2003*14+1988+2001*2002)/(2002+2002*503+504*2002) = 2 

khó hiểu quá.

\(\frac{2003\times4+1998+2001\times2002}{2002+2002\times1002+2002\times1003}\)

\(=\frac{2003\times4+2\times999+2001\times2\times1001}{2002.\left(1+1002+1003\right)}\)

\(=\frac{2\times\left(2003\times2+999+2001\times1001\right)}{1001\times2\times\left(1+1002+1003\right)}\)

\(=\frac{2003\times2+999+2001\times1001}{1001\times\left(1+1002+1003\right)}\)

\(=1\)

mk ko bít

(2002+1)x14+1998+2001x2002/2002x1+2002x503+504x(2002+1)

=2002x14+14+1998+2001x2002/2002x1+2002x503+504x2002+504

=2002x(2001+14)+14+1998/2002x(1+503+504)+504

=2015+14+1998/1008+504

=4027/1512

 2003 x 14 + 1988 + 2001 x 2002

=28042 + 1988 + 4006002

=4036032

 2002 + 2002 x 503 +504 x 2002

=2002 x 1 + 2002 x 503 + 504 x 2002

=2002 x (1 + 503 + 504)

=2002 x 908

=1817816
