6. Show that if n (a2" - 1)/(a² - 1), where a is an integer, a > 1, and p is an odd prime not dividing a(a? many pseudoprimes to any base a. (Hint: To establish that a"-1 = 1 (mod n), show that 2p| (n-1), and demonstrate that a2P = 1 (mod n).) 1), then n is a pseudoprime to the base a. Conclude that there are infinitely doprime to the base 2.
