Question

What is the subset of n elements set.
1. 2ⁿ
2. 3ⁿ
3. 4ⁿ
4. ∞ 

Answer 1

Correct Answer - Option 1 : 2ⁿ

Concept:

Set A is said to be a subset of Set B if all the elements of set A are also present in Set B. In other words, set A is contained inside Set B.

A subset is denoted by the symbol ⊆

Example: If set A has {1, 2} and set B has {1, 2, 3}, then A is the subset of B because elements of A are also present in set B.

 

The number of a subset of a set having 'n' elements is  2ⁿ
