If ` z_(1),z_(2),z_(3),z_(4)` are two pairs of conjugate complex numbers, then `arg(z_(1)/z_(3)) + arg(z_(2)/z_(4))` is

`(pi)/2`

`pi`

`(3pi)/2`

Text Solution

Verified by Experts

The correct Answer is:

`arg(z_(1)//z_(4))+arg(z_(2)//z_(3))=(arg_(1)-argz_(4))+(argz_(2)-argz_(3))=(argz_(1)+argz_(2))-(argz_(3)+argz_(4)=0`
