Q . n is a positive integer . Also (√ 3) ^ (-n) <1 / 81, is n < 12 ?
(1) n is odd
(2) n is a prime number
QA B but not sure
(1) n is odd
(2) n is a prime number
QA B but not sure
(V3)^-n<1/81
or (V3)^n>81
or (V3)^n>(V3)^8
so n>8
From 1..n can be 9,11,13 etc..not sufficient
From 2 n can be 11,13 etc..not sufficient
combining
n can be 11,13 etc..not sufficient
IMO ans is E
