I ran into such problem. Not sure if some one can help.(adsbygoogle = window.adsbygoogle || []).push({});

$$\sqrt{-i^2}=\sqrt{-1\times i^2}=\sqrt{-1\times -1}=\sqrt{1}=1$$

I also have

$$\sqrt{-i^2}=\sqrt{-1}\times \sqrt{i^2}=\sqrt{-1}\times i=i\times i=-1$$

Can anyone explain to me the inconsistencies?
