# How do you write the complex conjugate of the complex number 9 − 5i?

Apr 10, 2018

$9 + 5 i$
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 $9 - 5 i$ is $9 + 5 i$.
