Recall that complex exponentiation does follow the usual rules that we use in the real numbers. If each of is a complex number then Here . That is the principal value. So you want
Note that I used this identity: . Does this help? To to hopefully more directly answer the OP's question, recall that the real numbers are a subset of the complex numbers. So, the answer I detailed above is written in the complex notation and .

More accurately you have where k is an integer (slight modification of your identity ;)). If you substitute this, you'll find: which is multi valued (all real) with the principal value you already found.
