simplify the given expressions, then make a list of the like terms that appear in your final answer
4^n+4n4n^2 + (2^n2n)

This is really just like the other one  but simpler. You don't even need the brackets, assuming the question is written correctly:
4^n + 4n 4n^2 + 2^n  2n
(4n  2n = 2n, sp)
4^n + 2^n  4n^2 + 2n
