When x is equal to two, two squared plus one, u is equal to five. And then we can just evaluate this right over here. Let's see, this is going to be equal to the antiderivative of u to the third power is u to the fourth over four. We're gonna evaluate that at five and two. And so this is going to be five to the fourth over four minus two to the fourth over four. And then we could simplify this if we like. But we've just evaluated this definite integral.
