## Main Question or Discussion Point

plz tell me where is the error here-

1 = [tex]\sqrt{}1[/tex] = [tex]\sqrt{}(-1) (-1)[/tex] =[tex]\sqrt{}-1[/tex] [tex]\sqrt{}-1[/tex] = i[tex]^{}2[/tex] = -1

so we get 1= -1. what is the error here?

1 = [tex]\sqrt{}1[/tex] = [tex]\sqrt{}(-1) (-1)[/tex] =[tex]\sqrt{}-1[/tex] [tex]\sqrt{}-1[/tex] = i[tex]^{}2[/tex] = -1

so we get 1= -1. what is the error here?
