[1-1/97]*[1-1/98]*[1-1/99]*...*[1-1/1000]
(1-1/97) x (1-1/98) x (1-1/99) x (1-1/1000) = ..............
tìm tổng dãy sau (1-1/97)*(1-1/98)*(1-1/99)*...*(1-1/1000)
C =(1-1/97)x(1-1/98)x(1-1/99)x.....x(1-1/1000)
( 1-1/97)x( 1-1/98)x( 1-1/99 )x( 1-1/1000 )=......... các bạn jup mình nhé mình tick cho
< 1- 1/97 > x < 1 - 1/98> x <1 - 1/99 > x ...x < 1- 1/1000>
1+ 99/98 -98/97+ 1/97*98
A=1/2+1/3+1/4+....+1/100
B=99/1+98/2+97/3+....+2/98+1/99
99/1+98/2+97/3+................+2/98+1/99
1/2+1/3+1/4+.......................+1/99+1/100
