In the complex number 8 - 4i; 8 is the real part of the complex number and -4 is the imaginary part of the complex number.
What is a complex number?
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The complex number is:
= 8 - 4i
As we know, the complex number can be represented as:
Z = a + ib
Here Z is the complex number
a is the real part of the complex number
b is the imaginary part of the complex number
i is the iota i = √-1
On comparing we get:
a = 8
b = -4
For part A: The real part is 8
8 is the real part of the complex number
For part B: the imaginary part is -4
-4 is the imaginary part of the complex number
Thus, in the complex number 8 - 4i; 8 is the real part of the complex number and -4 is the imaginary part of the complex number.
