Question

a={1,3,2,7} then write any two subsets of A.​

Answer 1

Given: A set A = {1,3,2,7}

To find: Any two subsets of A

Solution: In mathematics, a set A is a subset of a set B if all elements of A are also elements of B. B is then a superset of A. It is possible for A and B to be equal. If they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion.

The symbol "⊆" means "is a subset of".

The symbol "⊂" means "is a proper subset of".

The subsets of A are {1}, {3}, {2}, {7}, {1,3}, {1,2}, {1,7}, {3,2}, {3,7}, {2,7}, {1,3,2}, {1,3,7}, {1,2,7}, {3,2,7}, {1,3,2,7}.

Hence, any two subsets of A are {1} and {3}.

Answer: {1}, {3}

Answer 2

Answer:

if A={1, 3,2,7} then write 4 subset of A
