Does not help at all. when I learned this it was explained easier than this. when I first saw this I didn't think it was the right one, so I read it and it is very complicated for people that might be younger than me. Here's a suggestion you should actually put the power instead of writing it, I think people will understand it better.
I don't get it I read about 3 times but still don't understand please have more explanation next time.
This is extremely helpful for equations. Thanks!
