WebSep 16, 2024 · Let w be a complex number. We wish to find the nth roots of w, that is all z such that zn = w. There are n distinct nth roots and they can be found as follows:. Express both z and w in polar form z = reiθ, w = seiϕ. Then zn = w becomes: (reiθ)n = rneinθ = seiϕ We need to solve for r and θ.
