![**Exercise: Set Theory Proof**
**Task:** Either provide a counterexample or prove using the algebra of sets:
\[
\forall A, B, C \subseteq U \quad \left( A \setminus (B \setminus C) = ((A \setminus B) \cup (A \cap C)) \right)
\]
**Explanation:** For all sets \(A\), \(B\), and \(C\) within a universe \(U\), prove the given equation or disprove it by finding a counterexample.
**Options:**
- Proven
- Disproven
This task involves exploring the properties of set difference and intersection to determine the validity of the given expression.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F004a8e3c-a278-4414-bbaf-77c8d726d7bd%2F1aaef252-8410-40b4-b42b-493537ac6ca1%2Ftt8xq9o_processed.jpeg&w=3840&q=75)
