# How do you find the conjugate of 7-5i?

Change the sign of the imaginary component to find that the conjugate of $7 - 5 i$ is $7 + 5 i$
The complex conjugate of $a + b i$ is $a - b i$, that is, you simply change the sign of the imaginary component. In this case we have $a = 7$ and $b = - 5$
so the conjugate of $7 - 5 i$ is $7 + 5 i$
