Question

Write all possible subsets of {1, 2, 3, 4, 5, 6}.

Let me help you a few:
{1,2,3,4,5,6} > { }, {1}, {2}, {3}, {4}, {5}, {6}, {1,2}, {1,3}, {1,4}, {1,5}, {1,6}, {2,3}, {2,4}, {2,5}, {2,6}, {3,4}, {3,5}, {3,6}, {4,5}, {4,6}, {5,6}, {1,2,3}, {1,2,4}, {1,2,5}, {1,2,6}, {1,3,4}, {1,3,5}, {1,3,6}, {1,4,5}, {1,4,6}, {1,5,6}, {2,3,4}, {2,3,5}, {2,3,6},{2,4,5}, {2,4,6}, {2,5,6}, {3,4,5}, {3,4,6}, {3,5,6}, {4,5,6}, {1,2,3,4}, {1,2,3,5}, {1,2,3,6}, {1,3,4,5} more possible subsets can add in this list.

Verified by Toppr

Let A={1,2,3}

Number of elements in A is 3

Hence n=3

Number of subsets of A=2

n

where n is the number of elements of the set A

=2

3

=8

The subsets of {1,2,3} are

ϕ,{1},{2},{3},{1,2},{2,3},{1,3} and {1,2,3}
