(1/2004 -1)(1/2003 -1)(1/2002 -1).(1/1001 -1)(1/1000 -1)
文字说.(2004分之1 减1)(2003分之1 减1)(2002分之1 减1)...(1001分之1 减1)(1000分之1 减1)
文字说.(2004分之1 减1)(2003分之1 减1)(2002分之1 减1)...(1001分之1 减1)(1000分之1 减1)
(1/2004 -1)(1/2003 -1)(1/2002 -1).(1/1001 -1)(1/1000 -1)
=(-2003/2004)(-2002/2003)(-2001/2002)...(-1000/1001)(-999/1000)
=(-1)^1005*999/2004
=-999/2004
=(-2003/2004)(-2002/2003)(-2001/2002)...(-1000/1001)(-999/1000)
=(-1)^1005*999/2004
=-999/2004
(1/2004 -1)(1/2003 -1)(1/2002 -1).(1/1001 -1)(1/1000 -1)
写过程(1/2004-1) (1/2003-1) (1/2002-1)...(1/1001-1) (1/1000-1)=
(1/2003-1)(1/2002-1)(1/2001-1)...*(1/1001-1)(1/1000-1)
(1\2004-1)乘(1\2003-1)乘1\2002-1)(乘┈(1\1001-1)乘(1\1000-1)等于多少啊
1.(1/2004-1)(1/2003-1)(1/2002-1)...(1/1001-1)(1/1000-1) 2.(-
(2003/1-1)×(2002/1-1)×(2001/1-1)×.×(1001/1-1)×(1000/1-1)=?
|1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|+|1/2001-1/20
化简:|1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|-|1/2001-1
|1/2003—1/2002|+|1/2004—1/2003|—|1/2004—1/2003|
2003+2002*2004分之2003*2004-1
2002/2002又2002/2003+1/2004
1/2001*2002+1/2002*2003+1/2003*2004+1/2004*2005+1/2005=?/?
