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 \( 2 \)\( \sqrt{27} \) - \( 2 \)\( \sqrt{3} \)
| 4\( \sqrt{27} \) | |
| 0\( \sqrt{27} \) | |
| 0\( \sqrt{9} \) | |
| 4\( \sqrt{3} \) |
