等于2,我们奥数今天才考
(1-1/2+1/3-1/4+1/5-...+1/99-1/100)/[1/(1+101)+1/(2+102)+1/(3
1-1/2+1/3-1/4+1/5-1/6+…+1/99-1/100 1/(101+1)+1/(2+102)+1/(3+
1-1/2+1/3-1/4+...+1/99-1/100/1/1+101+1/2+102+1/3+103+...+1/5
(1+1/1*3)*(1+1/2*4)*(1+1/3*5).(1+1/98*100)*(1+1/99*101)
(1+1/1+3)*(1+1/2*4)*(1+1/3*5)*.*(1+1/98*100)*(1+1/99*101)
(-1)+2+(-3)+4+(-5)+6+.+(-99)+100+(-101)+102
1/1*2*3+1/2*3*4+1/3*4*5+...+1/99*100*101
1/1*2*3+1/2*3*4+1/3*4*5+.1/99*100*101
(1-1/2+1/3-1/4+...+1/99-1/100)/(1/101^2-1^2+1/102^2-2^2+...+
1*2/1+2*3/1+3*4/1+.100*101/1 1*3/1+3*5/1+5*7/1+.+99*101/1 怎么
(1/1+101+1/2+102+……+1/50+150)÷(1-1/2+1/3-1/4+……+1/99-1/100)
1,2,3,...,99,100; 2,3,4,...,100,101; 4,5,6,...,101,102;...10
