Best ResponseYou've already chosen the best response.0for the conjugate of : \(z = 2 + 3i \) if \(z = a + i \ b\), then its conjugate \(\bar z\) or \(z^* = a  i \ b\)

Best ResponseYou've already chosen the best response.0you have \(z=2+3i \\\ = a+i b\) you now want \(\bar z\) or \(z^* = ai b \)

Best ResponseYou've already chosen the best response.0so a = and b = and thus you have the conjugate

Best ResponseYou've already chosen the best response.0go back a step if \(z=2+3i =a+i \ b\), what is a and what is b ... ?

Best ResponseYou've already chosen the best response.0which is \(z^∗=a−i \ b\)

Best ResponseYou've already chosen the best response.0that's the number you started with you are looking for its conjugate

Best ResponseYou've already chosen the best response.0you started with \(z=2+3i\) you want its conjugate you get there by simply reversing the sign of the imaginary part
