ASVAB Arithmetic Reasoning Operations on Radicals Practice Test 420736

Question 1 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 \( 6 \)\( \sqrt{50} \) - \( 3 \)\( \sqrt{2} \)

3\( \sqrt{-21} \)
3\( \sqrt{2} \)
3\( \sqrt{25} \)
27\( \sqrt{2} \)
