SUMMARY
The term "power set," denoted as P(A), refers to the set of all subsets of a given set A. The cardinality of the power set, |P(A)|, is calculated as 2^|A|, indicating that the number of subsets doubles with each additional element in set A. This exponential relationship is the basis for the nomenclature, as it reflects the "power" of set A in terms of its subsets.
