Solution:
We know that 27 ≡ 3 (mod 12)⇒ then a = b (mod n), then am ≡ bm (mod n) --------(1)
⇒
----------- (2)
-----------(3)
------------(4)
------------(5)
------------(6)
----------(7)
----------(8)
----------(9)
-----------(10)
----------(11)
Which gives that 9 is subtracted from 2740 then which is divisible by 12. then remainder is 9.
