Can someone let me know if I have this right?

Find the following.

^18sqrt(-2)^18

does it come out to 9 or does it just stay -2 because I am thinking it goes to 9 but I could be extremely wrong?

Is the equation$$\Large \sqrt[18]{-2}^{18}?$$

anonymous · Answer

Or I meant the answer comes out to 2 or 9. Yes, that is the correct form of the equation.

kinggeorge · Answer

Then it would remain as $-2$.

anonymous · Answer

Or would it convert into a positive 2? That's what I want to make sure.

kinggeorge · Answer

It would stay negative because the equation is equivalent to $$\Large (-2)^{18 \over 18} = (-2)^1=-2$$

Ohhh okay, that makes sense! Thank you so much, I appreciate it!
