Hello, This is my first post here. I am sorry if this is the wrong place for this question or if my phrasing is unclear. -x^n≠(-x)^n -x^n=-(x^2) I am slightly confused by this because at the level I am at right now (i.e. pre-calculus) and before, I have seen statements that contradict this. For example, I feel like I have been told from beginning algebra until now that -2^2=4. When is this true and when is it not? I suppose it is a matter of notation? Thank you.
