Question

According to complex number property
z bar = ?

Answer 1

Answer:

z bar = a - bi, if z = a + bi.

Step-by-step explanation:

Complex numbers deal with the imaginary numbers.

In this study, z bar represents the conjugate of the imaginary number z.

Suppose an imaginary number c = a + bi, where a and b are real numbers and i refers to iota or √-1 then, c bar represents a - bi.

Here, we mean, c bar has a negative coefficient of i.

If imaginary number d = e - fi, where i is iota, then e bar is e + fi.

In simple words, sign of the number with iota gets changed to negative of the existing once.

This, says : if z = a + bi

So,

$\bar{z}=a-bi$

In the same manner,

$\bar{(\bar{z})}$ = a+ bi.

Answer 2

if z=a+bi,so in (bar z)=a-bi.

Because,in conjugate z is convert into bar z,so,a+bi is convert into a-bi.
