#2+3i#

Explanation:

The complex conjugate of a complex number #a+bi# is #a-bi#.

It is very simple: you leave the real part alone, and change the sign of the immaginary one. So, in your case, #a=2# (and this is the part we'll leave untouched), and #b=-3# (and we will change sign to this). So,

#2-3i -> 2+3i#
