Cho A= (1+ 1/3) . (1+1/8) . (1+1/15)...(1+1/9999)
So sánh A với 2
Nhanh mk tk nha, cám ơn
A = 1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
B = 3/4 . 8/9 .15/16. ... 9999/10000
tính
a; A = 3/4 * 8/9 * 15/16 * ..............* 9999/10000
b; B = {1 - 1/21 } * { 1 - 1/28 } * {1 - 1/36 } * .......................*{ 1 - 1326}
c; C = { 1 + 1/1*3 } * { 1 + 1 / 2*4 } * { 1 + 1/3*5} * ...........................* { 1+ 1/99*101}
( 1 + 1/3 ) x ( 1 + 1/8 ) x ( 1 + 1/15 ) x ... x ( 1 + 1/9999 )
3/4.8/9.15/16.....624/625
(1+1/3).(1+1/8).(1+1/15).....(1+1/9999)
