Form a union for the following sets. K = {2, 3, 5, 8} L = {3, 5, 7}

A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K ∪ L.

You simply must combine the two sets together without repeating any of the same numbers.

K ∪ L = {2, 3, 5, 7, 8}.
