Abstract: In this article we use P. Samuel's purely inseparable descent techniques to study the divisor class groups of normal affine hypersurfaces of the form $ {z^p} = G({x_1},\ldots,{x_n})$ and develop an inductive procedure for studying those of the form $ {z^{p^m}} = G$. We obtain results concerning the order and type of these groups and apply this theory to some specific examples.
