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 \( 8 \)\( \sqrt{125} \) - \( 7 \)\( \sqrt{5} \)
| 33\( \sqrt{5} \) | |
| \( \sqrt{625} \) | |
| \( \sqrt{25} \) | |
| 56\( \sqrt{125} \) |
