(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2008)*(1-1/2009)*(1-1/2010)
(-1×1/2)+(-1/2×1/3)+(-1/3×1/4)+…+(-1/2008×1/2009)
(1-1/2)*(1/3-1)*(1-1/4)*(1/5-1)…(1/2009-1)*(1-1/2010)等于多少
初中计算题,难(1-1/2-1/3-……-1/2008)*(1/2+1/3+1/4+……+1/2009)-(1-1/2-
计算:(1-1/2)(1/3-1)(1-1/4)(1/5-1)……(1-1/2010)(1/2011-1)
计算:1+2+3+4+5+…+2009+2010/(1-1/1006)(1-1/1007)…(1-1/2009)(1-1
(1-1/2^)(1-1/3^)……(1-1/2007^)(1-1/2008^)
(1/2008-1)(1/2007-1)(1/2006-1)…(1/3-1)(1/2-1)
1+1\(1+2)+1\(1+2+3)+1\(1+2+3+4)+……1\(1+2+3+……2010)
计算:(1/2009-1)(1/2008-)(1/2007-1)……(1/3-1)(1/2-1)
用简便算法计算:(1-1/2-1/3-1/4-…-1/2010)×(1/2+1/3+1/4+…+1/2010)-(1-1
计算(1/2009-1)*(1/2008-1)*(1/2007-1)*……*(1/1000-1)
(1/2009-1)(1/2008-1)(1/2007-1)……(1/3)(2/1)计算
