Question

Complex conjugate of \( 3i - 4 \) is:

• A. \(-3i - 4\)
• B. \( 3i + 4 \)
• C. \(-3i + 4\)
• D. None of these

Hint:

The complex conjugate of \( a + bi \) is \( a - bi \), where \( i \) is the imaginary unit.

Answer 1

The Correct Option is C

Step 1: Understanding complex conjugates.
The complex conjugate of a complex number \( a + bi \) is \( a - bi \), where \( i \) is the imaginary unit.
Step 2: Apply the concept.
For the complex number \( 3i - 4 \), the complex conjugate is obtained by changing the sign of the imaginary part: \[ \text{Complex conjugate of } (3i - 4) = -3i + 4. \]
Step 3: Conclusion.
The correct answer is (C) \(-3i + 4\). Final Answer:} \(-3i + 4\).
