Please clarify me for this problem. As I have read a number of full adders required is = 2^n, where n = number of bit, then here 15 full adders. How? Please explain.

The one half-adder can add the least significant bit of the two numbers. Full adders are required to add the remaining 15 bits as they all involve adding carries.
