Step 1 :Indicate whether each pair are like radicals: \(3 \sqrt{2}\) and \(3 \sqrt[3]{2}\).
Step 2 :Like radicals are radicals that have the same index and the same radicand. In this case, the index of the first radical is 2 and the index of the second radical is 3, so they are not like radicals.
Step 3 :Final Answer: The correct answer is \(\boxed{\text{b unlike radicals}}\).
