(1/2008-1)×(1/2007-1)×(1/2006-1)×……×(1/3-1)×(1/2-1)
(1/2008-1)(1/2007-1)(1/2006-1)…(1/3-1)(1/2-1)
(1-1/2^)(1-1/3^)……(1-1/2007^)(1-1/2008^)
1、(1/2+1/3+……1/1007)*(1+1/2+……1/2006)-(1+1/2+……+1/2007)*(1/2
数学-(1/2008-1)(1/2007-1)(1/2006-1)…(1/3-1)(1/2-1)给我算式!
(1/2008-1)(1/2007-1)(1/2006-1)……(1/1001-1)(1/1000-1)
(1)1×2分之1 + 2×3分之1 + … +2007×2008分之1
计算:(1/2009-1)(1/2008-)(1/2007-1)……(1/3-1)(1/2-1)
计算:(1/2+1/3+……+1/2006)(1+1/2+1/3+……+1/2005)-
(1/2009-1)(1/2008-1)(1/2007-1)……(1/3)(2/1)计算
(1-1/2008)×(1-1/2007)×……×(1-1/1001)×(1-1/1000)
计算(1/2009-1)*(1/2008-1)*(1/2007-1)*……*(1/1000-1)
计算:(1/2+1/3+1/4+…+1//2006)(1+1/2+1/3+…+1/2005)-(1+1/2+1/3+1/
