WebDec 3, 2024 · 3. There are three cube roots of i. The value at e i π / 6 is simply one of the roots. To find all of the roots, you can add 2 π / 3 for each root to the angle of π / 6. Since one root is at π / 6, the next one will be at π / 6 + 2 π / 3 = 5 π / 6. The next one will be at 5 π / 6 + 2 π / 3 = 3 π / 2. With this last angle, the root is ... 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. WebCube Root of 54.
