n can take all values from 2 to 5
and n takes all even values after 5
for n=2,3,4,5 all powers of 11 are palindromes(mirror image numbers)
11,121,1331,14641
For n>5,
even nos can have palindromes such as 111111,222222...

well ur answer is certainly not possible....
a number with even digits like
11111111...................111111 or
99999999999999999...9 is always a palindrome and divisible by 11
