So this is going to be equal to pi times x to the fifth over 5. And we're going to go from 0 to 2. So this is going to be equal to pi times, this thing evaluated at 2. Let's see, 2 to the third is 8, 2 to the fourth is 16, 2 to the fifth is, let me actually just write it down, 2 to the fifth over 5 minus 0 to the fifth over 5. And this is going to be equal to, 2 to the fifth is 32. So it's going to be equal to pi times 32 over 5 minus, well this is just 0, minus 0, which is equal to 32 pi over 5. And we're done.
