Suppose that h is a positive integer. For an integer n≥ 2, define P h (n)=(1 ω (n)∑ p∣ n p prime p h) 1/h, where ω (n) denotes the number of distinct prime divisors of n. Let A h (x) be the set of all positive integers n≤ x with ω (n)> 1 such that P h (n) is prime and P h (n)∣ n. In this paper, we prove that x exp (2 h log x log log x)≤| A h (x)|≤ x exp ((1/2) log x log log x), which generalizes a result of Luca and Pappalardi for h= 1.
