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. You could view this as x to the negative two times the square root of x, times the square root of x. And then you might wanna use a product rule, but you could simplify this even better. You could say this is the same thing as x to the negative two times x to the 1 1⁄2 power.
