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 \( 5 \)\( \sqrt{75} \) - \( 9 \)\( \sqrt{3} \)

-4\( \sqrt{25} \)
45\( \sqrt{25} \)
16\( \sqrt{3} \)
45\( \sqrt{3} \)
