Question

Write the all subsets of A={1,2,3,4​}

Answer 1

Answer:

{{1},{2},{3},{4},{1,2},{2,3},{3,4},{4,1},{1,3},{2,4},{1,2,3},{2,3,4},{3,4,1},{4,1,2},{1,2,3,4},{}}

Answer 2

The subsets of set A are: {{1},{2},{3},{4},{1,2},{2,3},{3,4},{4,1},{1,3},{2,4},{1,2,3},{2,3,4},{3,4,1},{4,1,2},{1,2,3,4},{}}.

• Subsets are a topic of the mathematical notion of Sets. A set is a group of objects or components separated by angle brackets, such as  {a, b, c, d}
• If A is a collection of even integers and B is a collection of 2,4,6, then B is a subset of A, denoted by B⊆A, and A is the superset of B.
• For example, for a set A = {1,2}, the subsets will be {{1},{2},{},{1,2}}.
• If a set includes n elements, the number of subsets for that set is 2ⁿ, and the correct subset is 2ⁿ-1.
• Using the same formula, the number of subsets of set A will be 16, and the elements of the same are listed above.
