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 \( 7 \)\( \sqrt{125} \) - \( 2 \)\( \sqrt{5} \)
| 14\( \sqrt{625} \) | |
| 33\( \sqrt{5} \) | |
| 5\( \sqrt{625} \) | |
| 5\( \sqrt{0} \) |
