a. Since each element of the set {1,3,3,3,5,5,5,5} belongs to the set {5,3,1}, and each element of the set {5,3,1} belongs to the set {1,3,3,3,5,5,5,5}, we conclude that these sets are equal.


b. Since 1{{1}},1\notin\{\{1\}\}, we conclude that these sets are not equal.


c. Since ,\emptyset\notin\emptyset, we conclude that these sets are not equal.
