Alright, I've beaten the dead horse on this problem and I'm seeking some help.
the problem is exactly as follows
(-5x)^2 (5x)^2
---------------- Divided
(10x)^2 (-2x)^2
The solution is 25/16
I need to understand the following rule pertaining to this problem.
(-a)^n = a^n if n is even. I know that like -3^2 is positive and I realize that -3^16 is positive; because, n is positive; but, I'm lost understanding how that rule applies directly to this problem.
To take it 1 step further
HOW does (-5x)^2 = (5x)^2 ? that is what this problem is telling me on Wolfram and all of those sites. Then i am supposed to get 5x^4 from (5x)^2 and (5x)^2 ? because that - sign just "magically" disappears according to that rule? and the result is literally 5x^4 of the top piece of this problem? I'm just not seeing it please help me?
