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. Pause this video and think about how would you approach this if you wanna take the derivative with respect to x of the square root of x over x squared. Well, once again, you might say this is a quotient of two expressions, might try to apply the quotient rule, or you might recognize, well, look, this is the same thing. Let me just focus on what's inside the brackets.
