To solve the expression (1/2) • 4^2 - (4-6)/2, we start by evaluating the exponents:
4^2 = 4 • 4 = 16
Then, we can simplify the expression further:
(1/2) • 16 - (4-6)/2
= 8 - (-2)/2 [Evaluating 16 divided by 2]
= 8 + 2/2 [Changing the subtraction of -2 to addition of 2]
= 8 + 1 [Evaluating 2 divided by 2]
= 9 [Adding 8 and 1]
So, the value of the expression is 9.
