The conjugate of $z = 3 - 4i$ is:
A$3 - 4i$, the same complex number always shows
B$-3 + 4i$, the negative of the original complex value
C$3 + 4i$, with the imaginary part sign flipped on chart
D$-3 - 4i$, the negative of the conjugate of $z$ here
Answer & Solution
Correct answer: C. $3 + 4i$, with the imaginary part sign flipped on chart
Conjugate: flip sign of imaginary part. $\bar z = 3 + 4i$.
