Answer

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

Work Step by Step

Null' is the set of elements in U that are not in the null set, so null' is all elements of U {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}. The intersection of Null' and U is all elements they have in common, which is all elements of U {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}. The union of U and R is the combined set of elements that are in either set, which again is U {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}.
