Cryptography

Assuming that a message has been sent via the RSA scheme with $p = 37$, $q = 73$, and $e = 5$, decode the received message ``34.''

Using the RSA scheme with $p = 37$, $q = 73$, $e = 5$, and replacing the letters A, B, , Z by 01, 02, , 26, what number would be sent for the message ``RL''?

Explain why the message YES cannot be sent using RSA scheme with $p = 31$ and $q = 73$ using blocks of length 4.
