Solution

Let's go through the step-by-step simplification table to ensure clarity and correctness in each step:

1. Original Expression:

[(m¬n)(mn)]p[(m \to \neg n) \vee (m \wedge n)] \wedge p This is the starting point, and we aim to simplify this expression.

2. Apply the Implication Rule:

The implication m¬nm \to \neg n can be rewritten using the rule m¬n=¬m¬nm \to \neg n = \neg m \vee \neg n: [(¬m¬n)(mn)]p[(\neg m \vee \neg n) \vee (m \wedge n)] \wedge p This is the correct transformation from the original implication.

3. Apply the Associative Law:

We now combine the terms using the associative law of disjunction. The expression becomes: (¬m¬n(mn))p(\neg m \vee \neg n \vee (m \wedge n)) \wedge p We don't do much simplifying yet here; this step is primarily about grouping the terms.

4. Apply the Distributive Law:

Next, we distribute ¬m¬n\neg m \vee \neg n over the conjunction mnm \wedge n. This step involves expanding: (¬m¬nm)(¬m¬nn)p(\neg m \vee \neg n \vee m) \wedge (\neg m \vee \neg n \vee n) \wedge p Here, we break up the disjunction ¬m¬n(mn)\neg m \vee \neg n \vee (m \wedge n) into two parts as a distributive step. The logic is:

  • (¬m¬nm)(\neg m \vee \neg n \vee m) represents the first part, and
  • (¬m¬nn)(\neg m \vee \neg n \vee n) represents the second part.

5. Apply the Complement Law:

Now, we apply the complement law. We know that:

  • ¬mm=True\neg m \vee m = \text{True},
  • ¬nn=True\neg n \vee n = \text{True}.

Thus, the expression simplifies to: TrueTruep\text{True} \wedge \text{True} \wedge p

6. Apply the Identity Law:

Finally, applying the identity law, Truep=p\text{True} \wedge p = p, the expression simplifies to: pp

Final Result:

The simplified expression is pp.
