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 \( 3 \)\( \sqrt{112} \) + \( 8 \)\( \sqrt{7} \)
| 24\( \sqrt{7} \) | |
| 11\( \sqrt{16} \) | |
| 20\( \sqrt{7} \) | |
| 24\( \sqrt{112} \) |
