You are Eve. You notice that Alice has RSA public key (493, 31) and Bob has RSA public key (493, 27). You intercept the transmission CA = 284 from Ronald to Alice, and the transmissionCB = 326 from Ronald to Bob, and you are sure that they represent the same plaintext M. Find M. Show your steps.

Hint: When you have to raise a number to a negative exponent, use the standard interpretation that a^k = (a^1)^k.
