Let L1 = aaa, L2 = a,b,a,b,a,b,a,b, and L3 = L2. Describe the strings that are in the languages L2, L3, and L1 intersection L3.
a) L2: a, b, L3: ε, a, b, aa, ab, ba, bb, aaa, aab, aba, abb, baa, bab, bba, bbb, L1 ∩ L3: aaa
b) L2: a, b, L3: ε, a, b, aa, ab, ba, bb, aaa, aab, aba, abb, baa, bab, bba, bbb, L1 ∩ L3: a, b
c) L2: a, b, L3: ε, a, b, aa, ab, ba, bb, aaa, aab, aba, abb, baa, bab, bba, bbb, L1 ∩ L3: ε
d) L2: a, b, L3: ε, a, b, aa, ab, ba, bb, aaa, aab, aba, abb, baa, bab, bba, bbb, L1 ∩ L3: ∅
