The conformal relation between scale- invariant fourth-order gravity and Kaluza-Klein models as derived is applied to Friedmann cosmological models. Especially, the results that power-law inflation is an attractor solution can be carried over, but the conformal transformation brings power-law inflation to de Sitter-like exponential inflation, or power-law inflation a {approx} t. This paper reports that results depend essentially on the dimension of the internal space.
