(A) Given the conditions for set $A$:$1$. $x^2 = 16 \implies x = 4$ or $x = -4$.$2$. $2x = 6 \implies x = 3$.For an element $x$ to be in set $A$,it must satisfy both conditions simultaneously.Since there is no value of $x$ that satisfies both $x \in \{4, -4\}$ and $x = 3$,the set $A$ contains no elements.Therefore,$A = \phi$.
