ASVAB Arithmetic Reasoning Operations on Radicals Practice Test 813984

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 \( 2 \)\( \sqrt{27} \) + \( 2 \)\( \sqrt{3} \)

4\( \sqrt{81} \)
4\( \sqrt{27} \)
4\( \sqrt{9} \)
8\( \sqrt{3} \)
