What does this thing over here mean? Well, if I was taking the derivative, if I was taking the derivative of, let me write it this way, if I was taking the derivative of x to the third power, x to the third power with respect to x, if it was like that, well this is just going to be, and let me put some brackets here to make it a little bit clearer. If I'm taking the derivative of that, that is going to be, that is going to be, we bring the exponent out front, it's going to be three, three times x, three times x to the second power. Three times x to the second power. So the general notion here is, if I'm taking the derivative of something, whatever this something happens to be, let me just add a new color. It could be, I'm doing the derivative of orange circle to the third power with respect to orange circle, well that's just going to be three times orange or yellow circle. Let me make it an actual orange circle.
