Answer 2

Answer:

2^3 = 8

as P(A) = 2^n

Step-by-step explanation:

P(A) is the collection of all subset of a set A is called power set of A.

Thus, if A= {1,2}

P(A) = { ¢, {1}, {2}, {1,2} }

Also, note that n[P(A)] = 4 = 2^2

In general, if A is a set with n(A) = m , then it can be shown that n[P(A)] = 2^m
