Ta có:
\(\frac{2004}{2005}\times\frac{200520052005}{200320032003}\times\frac{20032003}{20042004}\)
\(=\frac{2004}{2005}\times\frac{2005}{2003}\times\frac{2003}{2004}\)
\(=\frac{2004\times2005\times2003}{2005\times2003\times2004}=1\)
Vậy giá trị biểu thức là 1
=2004/2005 x 2005/2003 x 2003/2004
=(2004x2005x2003)/(2005x2003x2004)
=1
2004/2005 x 200520052005/200320032003 x 20032003/20042004
=2004/2005 x 2005/2003 x 2003/2004
= 2004x2005x2003/2005x2003x2004
= 1( tử số = mẫu số nên p/s = 1 nha)
=\(\frac{2004}{2005}\)x \(\frac{2005}{2003}\)x \(\frac{2003}{2004}\)
=\(\frac{2004}{2003}\)x \(\frac{2003}{2004}\)
= 1
\(\frac{2004}{2005}\times\frac{200520052005}{200320032003}\times\frac{20032003}{20042004}\)
\(=\frac{2004}{2005}\times\frac{2005\times100010001}{2003\times100010001}\times\frac{2003\times10001}{2004\times10001}\)
\(=\frac{2004\times2005\times100010001\times2003\times10001}{2005\times2003\times100010001\times2004\times10001}\)
\(=1\)
\(\frac{2004}{2005}\times\frac{200520052005}{200320032003}\times\frac{20032003}{20042004}\)
\(=\frac{2004\times2005\times100010001\times2003\times10001}{2005\times2003\times100010001\times2004\times10001}\)
\(=1\)
\(\frac{2004}{2005}\cdot\frac{200520052005}{200320032003}\cdot\frac{20032003}{20042004}\)
\(=\frac{2004}{2005}\cdot\frac{2005}{2003}\cdot\frac{2003}{2004}\)
\(=\frac{2004}{2005}\cdot\frac{2005}{2003}\cdot\frac{2003}{2004}\)( cách gạch các số giống nhau đi ta được số )
\(=1\)
\(\frac{2004}{2005}\cdot\frac{200520052005}{200320032003}\cdot\frac{20032003}{20042004}\)
\(=\frac{2004}{2005}\cdot\frac{2005}{2003}\cdot\frac{2003}{2004}\)
\(=\frac{2004}{2005}\cdot\frac{2005}{2003}\cdot\frac{2003}{2004}\)
\(=1\)
