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 \( 8 \)\( \sqrt{80} \) + \( 3 \)\( \sqrt{5} \)
| 11\( \sqrt{16} \) | |
| 35\( \sqrt{5} \) | |
| 24\( \sqrt{80} \) | |
| 11\( \sqrt{400} \) |
