I'll be glad to check your answer.
Well first you need to do whats inside the parentheses first because of order of operations.
Lets take the denominator (top half) first.
4(2+1)^2
2=1=3
3^2=9
9x4=36
_______
Now take the second half.
(1)^2= 1
3x1=3
Now since it's in a fraction from 36 over 3, you simply divide the two numbers.
36/3 gives you a final answer of 12.
