Question 119853: I need some help with this problem I can figure it out without the negative sign but I am not sure what to do with the negative sign.
I have to evaluate if possible. The question is -sqrt81.
So I am thinking that -sqrt81 is a perfect square so the answer would be -0. If I am not right could you please help me figure it out.
