## Thinking Mathematically (6th Edition)

The set of subsets of {a, e, i, o, u} contains 64 elements The above statement is false. The number of subsets of a finite set can be found using the formula $2^{n}$ where n is the number of elements of the set. Since the given set has 5 elements, then it has $2^{5}$ = 32 subsets.
