Answer variants:

\{\sqrt{13}, \sqrt{15}, 7\}

\sqrt{13}, \sqrt{18}

\sqrt{18}

\{\sqrt{15}, 7, 15\}

\{\sqrt{15}, 7\}

Choose the associative property of intersection of sets for \(A\), \(B\) and \(C\) and find the set \(A \cap (B \cap C)\).

\(A\) \(=\)

\{\sqrt{13}, \sqrt{15}, \sqrt{18}, \sqrt{23}, 7\}

, \(B\) \(=\)

\{\sqrt{13}, \sqrt{15}, 7, 15, 23\}

and \(C\) \(=\)

\{\sqrt{15}, \sqrt{18}, 7, 13, 15\}
