Question 4 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 \( 5 \)\( \sqrt{32} \) - \( 9 \)\( \sqrt{2} \)

11\( \sqrt{2} \)
-4\( \sqrt{-12} \)
45\( \sqrt{2} \)
-4\( \sqrt{2} \)
