How can the empty set be a member of every power set but not also a member of every set? Also, isn't it true that (x ≠ ∅) → (x ∉ ∅) so that (x ∈ ∅) → (x = ∅) is also true (by way of Modus Tollens)? And wouldn't this therefore mean that the empty set is a member of every set, including...
5. Is the empty set a member of every power set? | CK-12 Foundation

Yes, the empty set is a member of every power set. The power set of a set @$\begin{align*}A\end{align*}@$ is the set of all possible subsets of @$\begin{align*}A\end{align*}@$. Since the empty set is a subset of every set, it is a member of every power set. In set theory, the power set of a set is the collection of all possible subsets of the set. It is denoted as @$\begin{align*}P(S)\end{align*}@$ or @$\begin{align*}2^S,\end{align*}@$ where @$\begin{align*}S\end{align*}@$ is the original set. Mathematically, if S is a set, the power set of @$\begin{align*}S\end{align*}@$ is defined as: @$$\begin{align*}P(S) = \{X: X \subseteq S\}\end{align*}@$$ This means the power set of @$\begin{align*}S\end{align*}@$ is the set of all sets that can be formed using the elements of @$\begin{align*}S,\end{align*}@$ including the empty set and @$\begin{align*}S\end{align*}@$ itself. For example, let's consider a set @$\begin{align*}A = \{3, 6\}.\end{align*}@$The power set of @$\begin{align*}A,\end{align*}@$ @$\begin{align*}P(A),\end{align*}@$ would be: @$$\begin{align*}P(A) = \{\emptyset, \{3\}, \{6\}, \{3, 6\}\}\end{align*}@$$ So, the power set of @$\begin{align*}A\end{align*}@$ includes the empty set, all the subsets with one element, and the set itself.
