Question

1. Find the power set of the set A={2,3,5). Moreover find the cardinal number
of power set.​

Answer 1

Step-by-step explanation:

A={2,3,5}

P(A)={{ } ,{2},{3},{5},{2,3},{2,5},{3,5} ,{2,3,5}}

$cardinality \: of \: power \: set \: = {2}^{n }$

where n is the number of elements in A

n(P(A)) = 2³ = 8
