    Does anybody have any idea which version of this proof is required for Higher Level Maths? There's two in my book for n an element of N and n an element of Z

    Once you're able to prove it for N, you can prove it for Z, you just use -n given that it's true for n. Proving for Z requires the fill proof for N plus the extra few lines about -n.

    An exam question will specify N or Z. You can't be asked to prove for Q but must know the result.

    You should definitely know the proof by induction of De Moivre's Theorem.
