Ned,
The indefinite integral of f(x)=x^(3/4) + x^(4/3) is
F(x) = (4/7)x^(7/4) + (3/7)x^(7/3) + C,
just as you said. Congratulations! I hope you can check such results yourself
by differentiating F(x) and getting f(x).
I wonder why your teacher uses the term "antiderivative" when the standard
term is "integral," which is half as long.

If f(x) = fourth_root(x^3) + cube_root(x^4), then
its most general antiderivative function, I thinks, is:
F(x) = 4/7x^7/4 + 3/7x^7/3 + C.
How far off am I, that is the question!
Cheers!
Ned
