$\emptyset'=\{ 1,2,3,4,5,6,7,8,9,10 \}$
$\bf{\text{Solution Outline:}}$ To get the elements of $\emptyset' ,$ get the elements of $U.$ $\bf{\text{Solution Details:}}$ The complement of the empty set, denoted by $\emptyset ',$ are all the elements of $U$ that are not in the empty set. These elements are the same elements of $U.$ Hence, \begin{array}{l}\require{cancel} \emptyset'=\{ 1,2,3,4,5,6,7,8,9,10 \} .\end{array}
