Question

If z = a - bi, which of the following must be true of the imaginary part of the complex conjugate of z?

a. It must be the opposite of -bi.
b. It must be the opposite of bi.
c. It must be the opposite of -b.
d. It must be the opposite of b

Answer 1

correct answer is c)

Explanation:

Answer 2

If z = a-bi, the complex conjugate of z is a + bi.

So the imaginary part is "b"

"b" is opposite of -b, so correct answer is c)
