If set A has 4 elements then find the number of elements in the power of set A

Answer 1

Step-by-step explanation:

If set has n elements then P(A) has 2^n elements

Now, if set A has 4 elements then P(A) has 2^4 = 16 elements

Answer 2

The number of elements in the power set A is 16.

Step-by-step explanation:

Consider the provided information.

It is given that the set A has 4 elements and we need to find the number of elements in the power of set A.

For a provided set S having n elements, the number of elements in power set P(S) is $2^n$.

Now substitute n = 4 in the above formula.

$2^4=16$

Hence, the number of elements in the power set A is 16.
