Math Problem Statement
çözer misin
Solution
This is a propositional logic statement:
P → (Q → P ∧ Q)
Let’s solve it step-by-step:
Step 1: Understand the logical formula
- P → (Q → P ∧ Q) means:
"If P is true, then if Q is true, P ∧ Q must also be true."
Step 2: Break it down using logical equivalences
-
Implication rewrite: The implication P → X is equivalent to ¬P ∨ X.
Rewrite the formula:
-
Distribute the parentheses:
Simplify ¬Q ∨ (P ∧ Q) using the distributive property:
(This step is true because ¬Q ∨ (P ∧ Q) means either ¬Q is true, or P and Q are both true. Simplifying this leads to ¬Q ∨ P ∨ Q.)
-
Combine terms:
Notice that ¬P ∨ (¬Q ∨ P ∨ Q) can be combined further:
- ¬P ∨ P simplifies to True (a tautology).
- ¬Q ∨ Q also simplifies to True (a tautology).
So the entire expression simplifies to True.
Final Answer:
The statement P → (Q → P ∧ Q) is always True (a tautology).
Would you like me to explain any specific part of the solution further?
