When introducing complex algebra, we postponed discussion of what it means to raise a complex number to a non-integer power, such as \(z^{1/2}\), \(z^{4/3}\), or \(z^{\pi}\). It is now time to open that can of worms. This involves learning about the two indispensible concepts of branch points and branch cuts.
