n Use the Pumping Lemma for Regular Languages to prove that this language is not regular: L= {an>0}. Use the string s = a" in your proof and cite Fermat's Last Theorem. Hint: Use Fermat's Last Theorem to choose a value for i that produces the contradiction. a. Start by stating the forms of x, y, and z. b. Show the contradiction using condition (1) of the PL, i.e. repeat the string y.
