Take this in two steps
First step is to evaluate (3 � 5)
Plug 3 and 5 into the definition for �
(A+B)/2
(3+5)/2
8/2 = 4
So, (3 � 5) = 4
Now take that result and plug it into the original equation
(3 � 5) � 8
4 � 8
Now evaluate that using the definition for �
(A+B)/2
(4+8)/2
12/2 = 6
The result is 6. Answer B
