So negative one times negative five is positive five. X to the, if we take one less than negative one, we're gonna go to the negative two power. So once again, making this algebraic recognition simplified things a good bit. Let's do a few more examples of just starting to recognize when we might be able to simplify things to do things a little bit easier. So let's say that someone said, hey, you, take the derivative with respect to x. And I'm using x as our variable that we're taking the derivative with respect to, but obviously this works for any variables that we are using. So let's say we're saying square root of x over x squared.
