Ok, so to get started, do you know how to multiply square roots together?
OpenStudy (anonymous):
The sqrt of -6, will equal to positive 6.
The sqrt of -18, will equal to positive 3.
Which will lead to your answer 6sqrt3.
OpenStudy (anonymous):
would the answer be complex?

OpenStudy (anonymous):
Meaning of non-complicated?

Usully, it's not necessary to put that as an answer but if you have an answer choice that needs a complex number then put it in. All I know is, don't put it for this problem.

Show me it.

I would say the first one.
OpenStudy (anonymous):
\[-6i \sqrt{3}\]
OpenStudy (triciaal):
i = sqrt of -1
rt of -18 = rt of -1*rt of 18
i^2 = -1
