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 \( 5 \)\( \sqrt{125} \) - \( 3 \)\( \sqrt{5} \)
| 15\( \sqrt{125} \) | |
| 2\( \sqrt{125} \) | |
| 2\( \sqrt{625} \) | |
| 22\( \sqrt{5} \) |
