(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)*……*(1+1/9)*(1+1/10)(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)*……*(1+1/9)*(1+1/1

(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)* …… *(1+1/9) * (1+1/10)
(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)* …… *(1+1/9) * (1+1/10)

(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)* …… *(1+1/9) * (1+1/10)
怎么没分的?
(1+1/2)*(1+1/3)*(1+1/4)*(1+1/5)* …… *(1+1/9) * (1+1/10)
=3/2*4/3*5/4*6/5*……10/9*11/10
=11/2
