The Attempt at a Solution



I have no idea where to start.

You could start with the definition of a deficient number.
If p is prime, it's only divisors are 1 and p and thus, the sum of it's divisors is p+1.
What are the divisors of pn?

would be P^n +P^1+P^0 correct?
 
If p is prime, then it's only divisors are 1 and p. The divisors of pn are also 1 and p, which sum to p+1. Apply this to the criteria of a deficient number.
