<prompt> Suluhu za z4 -16i zinaweza kuonyeshwa katika fomuanzaalignz_1 r_1 cos theta_1 i sin theta_1, z_2 r_2 cos theta_2 i sin theta_2, z_3 r_3 cos theta_3 i sin theta_3, z_4 r_4 cos theta_4 i sin theta_4,endalignambapo r_k 0 na 0circ le theta_k 360circ. Pata theta_1 theta_2 theta_3 theta_4, kwa digrii.  <response>: Kwanza, tunaweza kuandika z4 -16i 16 jina la operetacis 270circ.
