9/16
===========
Perform the operations in the correct order.
First, we evaluate the exponents:
- (1/2)³ = 1/8 and
- (1/4)² = 1/16
Then, we subtract the second term from the first:
- 1/8 - 1/16 = 2/16 - 1/16 = 1/16
Finally, we add the third term:
- 1/16 + 1/2 = 1/16 + 8/16 = 9/16
Therefore, the value of the expression is 9/16.
