18 is not a perfect square, so none of these are correct

Answer 1

The square root of 18 can be simplified as follows:

\[ \sqrt{18} = \sqrt{9 \times 2} = \sqrt{9} \times \sqrt{2} = 3\sqrt{2} \]

The square roots of 18 are both positive and negative. Therefore, the correct answers could be \(3\sqrt{2}\) and \(-3\sqrt{2}\), but none of the provided responses match that.

So, the closest response is:

18 is not a perfect square, so none of these are correct.
