Question 2 of 5
Adding & Subtracting Radicals

To add or subtract radicals, the degree and radicand must be the same. For example, \(2\sqrt{3} + 3\sqrt{3} = 5\sqrt{3}\) but \(2\sqrt{2} + 2\sqrt{3}\) cannot be added because they have different radicands.

What is \( 3 \)\( \sqrt{12} \) - \( 6 \)\( \sqrt{3} \)

0\( \sqrt{3} \)
18\( \sqrt{36} \)
18\( \sqrt{12} \)
18\( \sqrt{3} \)
