11. As a foreshadow into a topic from Chapter 5, let's define an "inverted operation" as NOT-OR (e.g., (a+b)) or NOT-AND (e.g., (ab)'). Use DeMorgan's Laws to remove all inverted operations from the following equations. You do NOT need to simplify further after applying DeMorgan's to inverted operations. a. w = xy + (y'z) + (x + y')' b. h=k(l+m')' + (k' + l)' + (1 + m) c. y = ((a'b')' + (a+b')')'
