Is that true?

What does "3" mean? Positive 3 or negative 3 or both?
anonymous
  • anonymous
I don't think that is related... I'm just saying that -6^2 and 6^2 both equal 36
Mertsj
  • Mertsj
It is related. the symbol does not indicate a sign so it is understood to be the positive root.
Mertsj
  • Mertsj
and also -6^2=-36 wheras (-6)^2=36
anonymous
  • anonymous
Oh wow, you are right, I immediately understood it to be positive, nice job. And you know i meant (-6)
