![SOLVED:It is easy to show that the converse of Fermat' s Theorem does not hold; i.e, the congruence a" =a (mod n) for all a does not imply that n is prime. SOLVED:It is easy to show that the converse of Fermat' s Theorem does not hold; i.e, the congruence a" =a (mod n) for all a does not imply that n is prime.](https://cdn.numerade.com/ask_images/92c6b113d60b4916a7913dae7abc4d45.jpg)
