Question

Which of the following expressions is the conjugate of a complex number with 2 as the real part and 3i as the imaginary part?

A. 2 + 3i
B.2 − 3i
C.3i + 2
D.3i − 2

Answer 1

The conjugate of the complex number is 2 − 3i.

Explanation:

Answer 2

The complex number is represented as 2 + 3i. The conjugate of the complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign. Therefore, the correct answer is option B. The conjugate of the complex number is 2 − 3i.
