1MA 03. NOMBRES COMPLEXOS/1MA.03.2 Nombres complexos 1MA.03.2.10DT FORMA BINOMICA

Forma binòmica

En forma binòmica, un nombre complex s'escriu:

z = a + bi on a és la part real, i b és la part imàginària.

bi és un nombre imaginari pur.

Dos nombres complexos són iguals, si tenen:

les parts reals iguals
les parts imaginàries iguals
