You can put this solution on YOUR website! Find all roots of the equation z^5 = i, i.e. find the five values of
i^1/5 and show them on an Argand diagram
------------------
z^5 = I = 1cis(90) + n*360, n = 0,1,2,3,4
z = 1cis(18, 90, 162, 234, 306) in degrees
z = cos(18) + isin(18), etc.
----------
--> pi/10, pi/2, 9pi/10, 13pi/10, 17pi/10 in radians
