I hope this is the way you used to do things, but don't do them that way now! Your equation [tex]\sqrt{1}^2=1[/tex] is incorrect on at least two counts:  [tex]1^2=1[/tex], so you're attempting to take the square root of 1. If you meant the square of 1, rather than the negative of 1 squared, put parentheses around 1.
 [tex]\sqrt{(1)^2}=+1, not 1[/tex]

well I meant [tex](\sqrt{1})^2[/tex]. Of course when I see i
^{2} I instantly think 1, and don't get into the nitty gritty of it
