First, solve the parentheses:
1/2 + 2 = 2 1/2 = 5/2
Next, square the result of the first step:
(5/2)^2 = 25/4
Finally, add the result of squaring the first step to half the sum of 4 and 7 1/2:
1/2(4+7 1/2) = 1/2(15/2) = 15/4 which is 3 3/4
Therefore, the final answer is:
25/4 + 3 3/4 = 25/4 + 15/4 = 40/4 = 10
