Question 3 of 5
Adding & Subtracting Radicals

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 \( 6 \)\( \sqrt{80} \) - \( 2 \)\( \sqrt{5} \)

4\( \sqrt{9} \)
4\( \sqrt{5} \)
4\( \sqrt{400} \)
22\( \sqrt{5} \)
