Which of the following is correct for any tow complex numbers `z_1a n dz_2?`
(a)`|z_1z_2|=|z_1||z_2|` (b) `a r g(z_1z_2)=a r g(z_1)a r g(z_2)` (c) `|z_1+z_2|=|z_1|+|z_2|` (d) `|z_1+z_2|geq|z_1|+|z_2|`

Text Solution

Verified by Experts

Since, it is known that

`abs(z_1z_2)=abs(z_1) abs(z_2),`

`abs(z_1z_2)=arg(z_1)=arg(z_2)`

and,
