[✓] Plot complex numbers?

GROUPS:

I have a very simple equation that I want to plot in Mathematica without Wolfram Alpha and I am having some trouble. This is the equation [ z^7 = 1 - i ] and I have used eq3 = Solve[{z^7 == 1 - i}, {z}] and found the answers

eq3 = Solve[{z^7 == 1 - i}, {z}]

{{z -> (1 - i)^(
   1/7)}, {z -> -(-1)^(1/7) (1 - i)^(1/7)}, {z -> (-1)^(2/7) (1 - i)^(
    1/7)}, {z -> -(-1)^(3/7) (1 - i)^(1/7)}, {z -> (-1)^(
    4/7) (1 - i)^(1/7)}, {z -> -(-1)^(5/7) (1 - i)^(
    1/7)}, {z -> (-1)^(6/7) (1 - i)^(1/7)}}

but I want to plot them now but Plot function doesn't plot it. I tried ContourPlot and DensityPlot and neither of these functions is plotting it. please help! I would really appreciate a link to the functions that plot this. I searched but I can't find anything

You may try Graphics or ListPlot:

eq3 = Solve[z^7 == 1 - I, z];
Graphics[Point[ReIm[z /. eq3]]]
ListPlot[ReIm[z /. eq3]]
