If \(A\) \(=\)

\{\sqrt{15}, \sqrt{19}, 5, 10, 15\}

, \(B\) \(=\)

\{\sqrt{10}, \sqrt{15}, \sqrt{19}, \sqrt{21}, 5\}

and \(C\) \(=\)

\{\sqrt{10}, \sqrt{15}, 5, 15, 21\}

, then find the following:

(i) \(A - (B \cup C)\) \(=\)

\{i\}

(ii) \(A - B\) \(=\)

\{i, i\}

(iii) \(A - C\) \(=\)

\{\sqrt{i}, i\}

(iv) \((A - B) \cap (A - C)\) \(=\)

\{i\}
