Let a be a regular expression of length n
Let α be a regular expression of length n. (a) Using procedures shown in class, if we convert α into a regular expression β such that L(β) = L(α). How long β might be? Give a reasonably tight upper bound.

Proof the theorem that the class of regular languages is closed under union; that is, if L1 is recognized by a NFA and L2 is recognized by a NFA, then L1 υ L2 is recognized by a NFA as well.

Let REGEXP be the language of valid regular expressions over {a, b}. That is, REGEXP is the set of all strings over the symbols Σ= {a, b, (,), U,*, ^} that are valid regular expressions. For example, the string “a (a U b)" is in REGEXP, whereas the string
