x^4=-81
 What is x?

 what about x^7 = -81 ?
 Using my own code:
 r0 = (1.68791,0.812857)
r1 = (0.41688,1.82647)
r2 = (-1.16807,1.46472)
r3 = (-1.87344,-1.63782e-07)
r4 = (-1.16807,-1.46472)
r5 = (0.416881,-1.82647)
r6 = (1.68792,-0.812856)
 p0 = (-81,-2.63931e-05)
p1 = (-81,-1.93183e-06)
p2 = (-81,2.25295e-05)
p3 = (-81,-4.69908e-05)
p4 = (-81,-0.000177025)
p5 = (-81,-7.53158e-05)
p6 = (-81,-0.000263285)
