Well, we could just algebraically use our exponent properties first, in which case, this is going to be equal to the derivative with respect to x of, if I'm taking x squared times sine of x to the third power, instead I could say x to the third to the third power, which is going to be x to the sixth, and then sine of x to the third power, sine of x to the third power. I'm using the same exponent property that we used right over here to simplify this. If I have, if I'm taking the product things to some exponent, well, that's the same thing of each of them raised to the exponent and then the product of the two. Now, how would we tackle this? Well, I, here, I would do the product rule first. So let's do that. So let's do the product rule.
