In Exercises \(1-6,\) a set \(S\) is defined recursively. Find four elements in each case. $$ \begin{array}{l}{\text { i) } 1 \in S} \\ {\text { ii) } x \in S \rightarrow 2^{x} \in S}\end{array} $$
Using the sets \(A=\\{a, b, e, h\\}, B=\\{b, c, e, f, h |, C=\\{c, d, f, g\\}, \text { and }\) \(U=\\{a, \ldots, h\\},\) find the binary representation of each set. $$ A \cup B $$

The empty set is a subset of every set. (Hint: Consider the implication \(x \in \emptyset \rightarrow x \in A .\) )
