A ring is an s-ring if (for
fixed s) As is an ideal whenever A is. We show that at least two different definitions
for the prime radical are equivalent in s-rings. If R satisfies (a,b,c) = (c,a,b) then R
is a 2-ring. In this note we investigate various properties of the prime and nil
radicals of R. In addition, if R is a finite dimensional algebra over a field of
characteristic ≠2 of 3 we show that the concepts of nil and nilpotent are
equivalent.
