Question

3 squareroot 3 + 5 squareroot 3
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A. 313 +513 = blank (Please type an exact answer, using radicals as needed.)
B. The radicals cannot be combined.

Answer 1

To add the terms \(3\sqrt{3}\) and \(5\sqrt{3}\), we can combine them because they have the same radical part.

\[ 3\sqrt{3} + 5\sqrt{3} = (3 + 5)\sqrt{3} = 8\sqrt{3} \]

So, the correct choice is:

A. \(3\sqrt{3} + 5\sqrt{3} = 8\sqrt{3}\) (Please type an exact answer, using radicals as needed.)

The answer is \(8\sqrt{3}\).
