Question
Using laws of logic prove that following are equivalent
and
Solution
To prove the equivalence and using laws of logic, we can follow these steps:
1. Break Down the Problem
We need to prove that: This is known as De Morgan's Law.
2. Relevant Concepts
We will use the following logical equivalences:
- De Morgan's Laws:
3. Analysis and Detail
Let's start with the left side of the equivalence:
- Begin with .
- According to De Morgan's Law, we can rewrite this as:
4. Verify and Summarize
The transformation holds according to the definitions provided by De Morgan's Laws. Thus, we have shown that: This concludes the proof.
Final Answer
Therefore, the two statements are equivalent:
