Question

SE
If n(A) = 4 then fine n[P(A)]​

Answer 1

Given:-

• n(A) = 4

⠀

To find:-

• n[P(A)]

⠀

Solution:-

Generally,

• the formula for finding the power of a set is 2ⁿ where n is the number of elements in the given set.

⠀

Now,

• understand what do you mean by this.

⠀

→ Power of a set = the maximum number of subset you can get from that set

⠀

According to the question,

⇛ n[P(A)]

⇛ 2n

⇛ 2⁴

⇛ 16

⠀

Hence,

• n[P(A)] = 16

⠀

More information:-

What is set:-

• A set is a collection of elements or numbers or objects, represented within the curly brackets { }.
