Question

Which of the following is the conjugate of a complex number with 4 as the real part and −3i as the imaginary part?

Answer 1

Answer:

$4+3i$

Step-by-step explanation:

we know that

To find the conjugate complex of a complex number, simply change the sign of the imaginary part of the complex number

In this problem we have

$4-3i$

so

the complex conjugate is equal to

$4+3i$

Answer 2

The conjugate of a complex number $z=a+bi~(a,b\in\mathbb{R})$ is $\overline{z}=a-bi$. So, for the complex$z=4-3i$, the conjugate is $\overline{z}=4+3i$.
