please help to solve these two discrete mathematics questions:

note: You will have to select values for e and d in this assignment. You should select single-digit values (the primes have been chosen so this is always possible). If you pick values for either e or d that are larger than this

for q4. a and c use public key = 7, 65 and message = 14 10 18 20 15 14

3. Encoding and decoding a message. (a) (b) To encode a message using a public key (6,71), we express the message as a number m. We then calculate the coded message 0 by nding came (modn), 0Sc<.>
