Using the property of sets prove that A intersection (A union B) is equal to A?

Using the property of sets prove that A intersection (A union B) is eq...
Proof that A ∩ (A ∪ B) = A:
1. Definition of Intersection and Union:
- Intersection (A ∩ B) of two sets A and B contains all elements that are in both sets.
- Union (A ∪ B) of two sets A and B contains all elements that are in either set.
2. Property of Union:
- A ∪ B includes all elements in set A and all elements in set B.
3. Property of Intersection:
- A ∩ (A ∪ B) will include only the elements that are common to both A and (A ∪ B).
4. Explanation of A ∩ (A ∪ B):
- A ∪ B includes all elements in A, so A ∩ (A ∪ B) will include all elements that are in both A and (A ∪ B).
- Since A is already a subset of (A ∪ B), the intersection of A and (A ∪ B) will only include elements that are in A.
5. Conclusion:
- Since A ∩ (A ∪ B) includes only elements that are in both A and (A ∪ B), and (A ∪ B) includes all elements in A, the intersection A ∩ (A ∪ B) will be equal to A.
Therefore, by using the property of sets, we have proven that A ∩ (A ∪ B) is equal to A.
