For a positive integer $n$ we write $φ (n)$ for the Euler function of $n$ . In this note, we show that if $b > 1$ is a fixed positive integer, then the equation $φ (x \frac{b^{n} - 1}{b - 1}) = y \frac{b^{m} - 1}{b - 1}, where x, y \in {1, ..., b - 1},$ has only finitely many positive integer solutions $(x, y, m, n)$ .

We show that $n^{2} + 1$ is powerfull for $O (x^{2 / 5 + ϵ})$ integers $n \leq x$ at most, thus answering a question of P. Ribenboim.
