(1—1/2)*(1-1/3)*(1-1/4)*...*(1-1/2010)*2010
(1—1/2)*(1-1/3)*(1-1/4)*...*(1-1/2010)*2010
计算:(1-1/2)(1/3-1)(1-1/4)(1/5-1)……(1-1/2010)(1/2011-1)
(1-1/2)*(1/3-1)*(1-1/4)*(1/5-1)…(1/2009-1)*(1-1/2010)等于多少
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
如下:2010*(1-1/2)*(1-1/3)*(1-1/4)*(1-1/5)*.*(1-1/2010)
计算(1/2-1)×(1/3-1)×(1/3-1)×(1/4-1)×.×(1/2010-1)×(1/2011-1)等于多
1/(1*2010)+1/(2*2009)+...+1/(2010*1)-(2010/2011)*(1/1*2009+1
(1/2+1/3+1/4+...+1/2010)(1+1/2+1/3+...+1/2009)-(1+1/2+1/3+..
1+1\(1+2)+1\(1+2+3)+1\(1+2+3+4)+……1\(1+2+3+……2010)
2010·(1-1/2)·(1-1/3)·(1-1/4)·…·(1-1/2010)
2010*(1-1/2)*(1-1/3)*…*(1-1/2010)=?(*=乘号)
(1+2/1)(1+4/1)(1+6/1).(1+10/)(1-3/1)(1—5/1).(1-9/1)
