d) Show that aaaa, baab = L(M₂).
e) Show that aaa, ab do not belong to L(M₂).

Theory that deals with fundamental questions around what problems can and cannot be solved using computation and uses a model of computation to understand the degree to which computers can assist in solving problems. There are three main branches of this subject: automata theory and formal languages, computational complexity theory, and computability theory.
