Math Problem Statement
Solution
The problem provided in the image asks to prove the following logical equivalence:
Here is the proof using logical equivalences:
Left-hand side:
- Distributive Law: Expand using the distributive property:
Right-hand side:
-
Associativity of : Rearrange the right-hand side (associativity allows this):
-
Absorption Law: Simplify : So:
-
Idempotence and Absorption Laws: Simplify further:
- (commutativity of ).
- Thus:
Now both sides match, completing the proof:
