Question: (i) Using the fact that 187 11- 17, show that 2186 = 174 mod 187. This shows that 187 fails the base 2 primality

(i) Using the fact that 187 11- 17, show that 2186 =

(i) Using the fact that 187 11- 17, show that 2186 = 174 mod 187. This shows that 187 fails the base 2 primality test. (ii) Compute 21911 mod 1911. Use Fermat's little theorem and hand calculations. Does 1911 pass or fail the base 2 primality test? You may use the prime factorization of 1911.
