Final answer:
The modulus n for the RSA algorithm is calculated as the product of p and q, which equals 65, and the totient z is the product of (p - 1) and (q - 1), which equals 48.
Step-by-step explanation:
The student's question involves calculating values used in the RSA encryption algorithm: the modulus n and the totient z. Given prime numbers p = 5 and q = 13, the modulus n is found by multiplying p and q, resulting in n = 65. The totient z is the product of (p - 1) and (q - 1), which results in z = 48. These values are essential for generating the public and private keys in RSA.
