We have the same bounds of integration. We have the same variable of integration. And actually we have this pi over here, so we could factor that out. And so this is the same thing as pi times the integral from zero to 1 1⁄2 of one minus f of x, one minus f of x squared minus one minus g of x, one minus g of x squared, and then all of that dx. And then, and actually you probably would want to do this, you probably would want to do this if you're taking the AP exam, not just leave it in terms of f of x and g of x. You would actually want to write the expressions for what f of x, f of x, and g of x are. So really the best answer would probably be pi times the integral from zero to 1 1⁄2 times one minus, well f of x is eight x to the third power, eight x to the third power squared, minus one minus g of x, g of x is sine of pi x, that squared, that squared, times dx.
