Answer:

#9 + 5i#

Explanation:

While complex numbers can be difficult to think about and occasionally difficult to use, the process of finding a complex number's conjugate is quite easy.

The conjugate of a complex number is a different complex number with the same real part and the imaginary part with an opposite sign. For example, the conjugate of #alpha + beta i# is #alpha - beta i#.

Thus, the complex conjugate of #9 - 5i# is #9 + 5i#.
