Which of the following is the conjugate of a complex number with 5 as the real part and −2 as the imaginary part?
ololo11 [35]

Hello!

Given two real numbers "a" and "b", the complex number z is defined as:

The complex conjugate of "Z = a + bi" is "Z = a – bi"

Given the complex number Z = a - bi, "a" is called the real part and "b" the imaginary part.

Therefore:

Re(a) = 5

Im(b) = -2

z = a - bi

z = 5 - (-2)i

\boxed{\boxed{z = 5 + 2i}}\end{array}}\qquad\checkmark

Answer: 

a. 5 + 2i
