Answer 2

Given:

A={x,y}

To Find:

Find n [p(A)]

Solution:

It is given that the set A={x,y} and we have to find n [p(A)] which signifies the number of elements in the power set of A, ( A set is a collection of elements which can be numbers, alphabets, etc.)

Now the power set of A will be, ( A power set is a set with elements as all the subsets of the given set)

P(A)=[{x},{y},{x,y},{}]

Now the n[p(A)] is defined as the number of all the elements present in the set, which for this case will be,

n[P(A)]=n[{x},{y},{x,y},{}]

          =4

Hence, the value of n[p(A)] is 4.
