On the $k$-free values of the polynomial $xy^k+C$

Consider the polynomial $f(x,y)=xy^k+C$ for $k\geq 2$ and any nonzero integer constant $C$. We derive an asymptotic formula for the $k$-free values of $f(x,y)$ when $x, y\leq H$. We also prove a similar result for the $k$-free values of $f(p,q)$ when $p,q\leq H$ are primes. The strongest tool we use is a recent generalization of the determinant method due to Reuss.
