%X There exist in the literature various exact formulae for the primecounting function ¦Ð(x) and the n-th prime pn. These formulae use thefloor function. In this note we present exact formulae for the perfectpower counting function N(x) and the n-th perfect power Pn. Theseformulae also use the floor function.
