Well, y is equal to the principal root of x. You could also write this as y is equal to x to the 1 1 2 power. We could just use the power rule. The derivative of y with respect to x is 1 1 2 x to the negative 1 1 2. So let me write that down. 1 1 2 x to the negative 1 1 2. And then times the derivative of x with respect to t. Times the derivative of x with respect to t. So let's see, we wanna find what we have here in orange.
