Question 1076605
Please help me find the possible? [sic] solutions for the equation of {{{ x^4 - 625i = 0 }}}. Could you list these solutions graphically?
------------
--> find the 4 4th roots of 625i.
625i --> 625cis(90)
4th roots are 5cis(90/4), 5cis(450/4), 5cis(810/4) and 5cis(1170/4)
----
= 5(cos(22.5) + isin(22.5)), etc
==================================================
Could you list these solutions graphically?
----
IDK what that means.
There are 4 solutions, not "possible" solutions.
