@helpme1.2 anyway you can help me with this one too?
OpenStudy (anonymous):
that would be A) 2+3i
OpenStudy (fernandez555):
@helpme1.2 thank you so much, could use all the help i can get.
OpenStudy (anonymous):
The complex conjugate of a + bi is a – bi, and similarly the complex conjugate of a – bi is a + bi. so the original would be 2+3i, so its complex conjugate is 2-3i sorry for the other mistake so it should be B
