what are the subsets of the set {2,5}?
A set has a number of subsets equal to 2^n, where n is the number of elements in the set. For the set {2,5}, which has n = 2 elements, there are 2^2 = 4 subsets.
The subsets of the set {2,5} are:
1. The empty set: {}
2. The set containing only 2: {2}
3. The set containing only 5: {5}
4. The set containing both 2 and 5: {2,5}
These are all the possible subsets for the set {2,5}.
