    Find a scalar function f(x,y) such that ∂f/∂x = 2xy3+8 and 

    ∂f/∂y = 3x2y2+2e2y. This requires but integrations, which you know how to do. So, what f(x,y) have you found?

    Since you found one, then F is conservative. 

    Now, knowing that F is conservative, you can evaluate any line integral by just using the potential function f(x,y) you found. Whats the procedure? What do you get?
