Using an RSA code with the encryption integer e = 3 and distinct primes 3, 41 encode the message M = 5. Determine the decryption integer and check your encoded message by decoding it.

to get the decryption integer:

mod n (3-1) * (41-1) = 80

e*d = 1 mod 80

3*d = 1 mod 80

d = 27

to check message

im not sure how to do any help please?
