Take the antiderivative here, so this is going to be t to the fourth over 4, t to the fourth over 4. And then this is going to be, if we increase the exponent here by 1, it's t to the third, and then you divide by 3. So it's negative 6 divided by 3 is negative 2t to the third, and then plus 300t, 300t, and I'm going to evaluate it. I am going to evaluate it at 10, and subtract from that, and evaluate it at 0. And so this is going to be equal to 1 tenth, that same 1 tenth there. And when you evaluate all of this at 10, what are we going to get? Let's see, 10 to the fourth power is 10,000 divided by 4 is 2,500.
