Question

Daca poate cineva va rog sa-mi explicati cum se rezolva

Answer 1

i^3 =i*i^2=i*(-1)=-i

1/i = (1*i)/(i^2) = i/(-1) = -i

z= -i -3i - 3 = -3 - 4i => conj = -3 + 4i

Answer 2

1/i=-i²/i=-i

3i³=-3i (pt ca i³=i²*i=(-1)*i=-i)

atunci z=-i-3i-3=-3-4i

si z conjugat =-3+4i

as  complex as that!!!
