Why does -3^2*(-3)^2 = -81 ?
Whereas both -3^2 and (-3)^2 both equals 9. I've run the equation in wolfram alpha and it does indeed give the results stated above.

From the link from a comment from FheFungusAmongsUs
−x^2, in every mathematical context I have seen, always means −(x^2). So −3^2=−9.

I was confused myself and put it into my browser to see very basically if it returned the same and it did. I know this isn't an answer but at least it doesn't seem like a wolfram problem. I may be looking at your question too much like a software engineer though.
