Consider the complex numbers in the complex plane below:
Some of these complex numbers are 54th roots of unity. Enter those complex numbers in any order, separated by commas. Use the letters to refer to the complex numbers; do not write them in or form.
I think just v
36054=6.˙6degrees
So there will be a 54th root of 1 at 1+0i
then there will be one every 6.666.. degrees around the unit circle.
That graph is split into 24 sectors 360/24 = 15 degrees each
so we need integers such that 15x=6.666.. y where x is between 0 and 24 and x and y are both integers
The only one that works is 180 degrees
15*12 = 27*6.6666
So the only answer is v
