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 \( 8 \)\( \sqrt{175} \) - \( 4 \)\( \sqrt{7} \)
| 32\( \sqrt{175} \) | |
| 32\( \sqrt{25} \) | |
| 36\( \sqrt{7} \) | |
| 4\( \sqrt{1225} \) |
