Answer :
Final answer:
The intersection of two undecidable languages L1 and L2 does not necessarily mean their intersection L will be undecidable; this depends on the specific properties of L1 and L2.
Explanation:
The intersection of two undecidable languages, L1 and L2, to form a new language L, has important implications in computer science and formal language theory. Assuming L1 and L2 are undecidable means that there is no algorithm that can determine for any given string whether that string belongs to either L1 or L2.
The significance of the intersection L = L1 ∩ L2 is that L may also be undecidable. However, this is not guaranteed merely because both L1 and L2 are undecidable. There exist cases where undecidable languages can intersect in a way that results in a decidable language. Therefore, the undecidability of the intersection L depends on the specific properties of L1 and L2. This highlights the complexity and counterintuitive nature of decidability in formal languages.
