Answer 1

this is correct answer.....

take care babes

Answer 2

answer= principal are (Z1 Z2)

= a + b is equal to 2 n π

= a + b π

Step-by-step explanation:

let Z1 and Z2 B2 complex number with A and B as their principal argument such that a + b<π, then principal are (z1 z2) is given by

A+B+π

a+b-π

a+b
