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 \( 3 \)\( \sqrt{50} \) + \( 3 \)\( \sqrt{2} \)
| 6\( \sqrt{2} \) | |
| 6\( \sqrt{25} \) | |
| 6\( \sqrt{50} \) | |
| 18\( \sqrt{2} \) |
