And so here, once again, we took something that we thought we might have to use a quotient rule or use the product rule, and now this just becomes a straightforward using the power rule. So this is just going to be equal to, so bring the negative 3 1⁄2 out front, negative 3 1⁄2, x to the negative 3 1⁄2 minus one is negative 5 1⁄2 power. So once again, just before you just, especially if you're about to apply the quotient rule and sometimes even the product rule, just see, is there an algebraic simplification, sometimes a trigonometric simplification, that you can make that eases your job, that makes things less hairy? And as a general tip, I can't say this is gonna be always true, but if you're taking some type of an exam and you're going down some really hairy route, which the quotient rule will often take you, it's a good sign that, hey, take a pause before trying to run through all of that algebra to apply the quotient rule and see if you can simplify things. So let's give another example. And this one, there's not a must, there's not an obvious way, and it really depends on what folks' preferences are. But let's say you wanna take the derivative with respect to x of one over two x to the negative five.
