Complex Numbers And Quadratic Equations question 408
Question: If $ z_1 $ and $ z_2 $ be two complex number, then Re $ (z_1z_2)= $
Options:
A) Re $ (z_1).Re(z_2) $
B) Re $ (z_1) $ . Im $ (z_2) $
C) Im $ (z_1).Re(z_2) $
D) None of these
Show Answer
Answer:
Correct Answer: D
Solution:
If $ z_1 $ and $ z_2 $ be two complex number then Re $ (z_1z_2)=Re(z_1)Re(z_2)-Im(z_1)Im(z_2) $
