First Step:
I believe here it is important to firstly look at each equation on its own and just try to think how the examiner would want you to answer this type of question.
Convert the general complex number z=x+iy to modulus-argument form.
Modulus-argument form implies that we should express z in terms of its straight line distance from the origin and the angle this straight line would make with the x axis. This is expressed as z = r e
