ℝ(3-7i)^4

Is this asking for just the real part of this complex expression? I suppose I could go about expanding the whole thing out, but is there a more convenient method? We've learnt a few methods, such as expressing it in polar form and such. But here the angle would be tan inverse of (-7/3) which renders it to some -66.80140949...

which makes it pretty hard to express in nice Pi angles.
