Question

Define powerset of a set​

Answer 1

Step-by-step explanation:

mathematics, the power set of a set S is the set of all subsets of S, including the empty set and S itself. In axiomatic set theory, the existence of the power set of any set is postulated by the axiom of power set. The powerset of S is variously denoted as P(S), (S), P(S), {\displaystyle \mathbb {P} }, ℘, or 2S. Wikipedia
