Question

iv) Find the absolute value of
a + ib by a-ib

​

Answer 1

Answer:

The absolute value of a complex number, a + bi (also called the modulus) is defined as the distance between the origin (0, ... −2+3i |=√(−2)2+32 =√4+9 =√13.

Answer 2

Step-by-step explanation:

Let z = a + ib be a complex number. Then, the modulus of a complex number z, denoted by |z|, is defined to be the non-negative real number.

√

a2+b2

modulus of a complex number z = |z| =

√

Re(z)2+Im(z)2

where Real part of complex number = Re(z) = a and

Imaginary part of complex number =Im(z) =b

|z| =

√

a2+b2
