Which of the following is the conjugate of 10 - 3i?

Solution:

Conjugate of a complex number is the number with the same real part but the negation of the complex part.

The conjugate of a complex number is that a complex number that has an equal real part and an imaginary part has the same magnitude but opposite in direction.

Thus, going with the above definition, the conjugate of the complex number can be easily found out.

The real part of the complex number = 10

Imaginary part of the complex number = -3

The real part of the conjugate of complex number = 10

Imaginary part of the conjugate of complex number = +3

Thus, the conjugate of the complex number will be 10 + 3i

Which of the following is the conjugate of 10 - 3i?

Summary:

The conjugate of the complex number will be 10 + 3i.
