forall A, B ve C isin (A cup B) cap C neq A cup(B cap C) midir?

The correct answer is:<br /><br />$(A\cup B)\cap C=\neq 1,\cup (A\cup C)$<br /><br />Explanation:<br />- The expression $\sqrt{4}$ simplifies to $2$, and $15\sqrt{2}$ remains as it is.<br />- The set operation $(A\cup B)\cap C$ represents the intersection of the union of sets $A$ and $B$ with set $C$. The symbol $\neq$ indicates that the result is not equal to $1$.<br />- The union operation $\cup (A\cup C)$ represents the union of sets $A$ and $C$.<br /><br />Therefore, the correct answer is $(A\cup B)\cap C=\neq 1,\cup (A\cup C)$.
