So then I'm just gonna multiply by u prime of x, which is three x squared plus, three x squared plus eight x. And so, well, I can clean this up a little bit. So this would be equal to, this would be equal to, actually, let me just rewrite that exponent there. So this 1 4th minus one, I can rewrite it, 1 4th minus one is negative 3 4ths. Negative 3 4ths. Negative 3 4ths power. And you could manipulate this in different ways if you like, but the key is to just recognize that this is an application of the chain rule.
