$$\sqrt{-2i}$$                                Just a thought. Don't take it as completely correct

anonymous · Answer

Can you show me how you got to that?

I cheated and used a calculator hope this helps or is correct and stuff

anonymous · Answer

Divide the 2 on both sides and you'll have $$\sqrt{x}=-2$$ then square both sides to remove the radical and you'll end up with $$x=4$$ My apologies

anonymous · Answer

so what are the extraneous?

anonymous · Answer

And that cannot be right anyway. it would be 2/x (that is the square root sign) -4. so it would be /x = 8 right?

anonymous · Answer

Oh wait, i see what you did now. Okay, i still need extraneous solutions though.

anonymous · Answer

Yeah

anonymous · Answer

I thought it was -8 because -8/2=-4

anonymous · Answer

one moment and I'll have the answer
