@helpme1.2 anyway you can help me with this one too?

anonymous · Answer

that would be A) 2+3i

@helpme1.2 thank you so much, could use all the help i can get.

anonymous · Answer

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
