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. Solve the following two equations: rn = s einθ = eiϕ The solutions to rn = s are given by r = n√s.

WebWe can use rational (fractional) exponents. The index must be a positive integer. If the index is even, then cannot be negative. We can also have rational exponents with numerators other than 1. In these cases, the exponent must be a fraction in lowest terms. We raise the base to a power and take an n th root.
