Question

According to complex number property
|z| = ?

Answer 1

Answer:

Real and imaginary part of a complex numbers: According to the definition if the complex number (a, b) be denoted by z then z = (a, b) = a + ib (a, b ϵ R) where a is called the real part, denoted by Re(z) and b is called imaginary part, denoted by Im (z).

Answer 2

Definition of Modulus of a Complex Number: Let z = x + iy where x and y are real and i = √-1. Then the non negative square root of (x2+ y 2) is called the modulus or absolute value of z (or x + iy).
