1. If the total number of proper subsets of a set
consisting of 5 elements is in the form of a^b-c
then the value of a + b + c is​

Answer 1

Answer:

If a set contains ‘n’ elements, then the number of proper subsets of the set is 2n - 1.

If A = {p, q} the proper subsets of A are [{ }, {p}, {q}]

⇒ Number of proper subsets of A are 3 = 22 - 1 = 4 - 1

In general, number of proper subsets of a given set = 2m - 1, where m is the number of elements.
