Use the binomial theorem to expand the expressions:

The correct answer is: (4g+2h)^4 = 256g^4 + 512g^3 h + 384g^2 h^2 + 128gh^3 + 16h^4

ANSWER:
Hint:
The binomial expansion is ,
We are asked to find the expansion of   using Binomial theorem.
Step 1 of 2:
The given expression is. Here, the value of n = 4, so we would have 4+1 = 5 terms in the expansion. The values are.
Step 2 of 2:
Substitute the values in the binomial equation to get the terms of the expansion; 
Thus, the expansion of the expression is 
Note:
The answer can also be found using the Pascal’s triangle. For the expansion of the expression (x+y)ⁿ , we would consider the (n+1)th row in the triangle.
