The conjugate complex number of 1 / (3-5i) is?

The conjugate complex number of 1 / (3-5i) is?

It is 1 / (3 + 5I). The conjugate of a complex number is to replace the original I with (- I)
When m is a real number, m square (1 + I) - M (5 + 3I) + 6 is (1) a real number? (2) in the fourth quadrant? (3) on the line y = x?
m^2(1+i)-m(5+3i)+6
=m^2-5m+6+(m^2-3m)i
1) When m ^ 2-3m = 0, that is, M = 3 or 0, the number is real
2) When m ^ 2-5M + 6 > 0
M ^ 2-3m3 or m ^ 2-3m3
The complex numbers corresponding to vertices a and B of a square ABCD are 2-3i and 5 + 2I. Find the complex numbers corresponding to the other two vertices
OA=2-3i OB=5+2i
∴AB=OB-OA=3+5i
ABCD is a square
∴|AB|=|AD| AB⊥AD
That is: ad = - 5 + 3I
∵AD=OD-OA
∴OD=OA+AD=(2-3i)+（-5+3i）=-3
Similarly, OC = ob + BC = 5I
In the complex plane, AB and AC correspond to - 1 + 2I and - 2-3i, respectively, so BC corresponds to? 1 + 2I and? 2-3i?
(arrow from left to right)
BA=1-2i
AC=-2-3i
BC=BA+AC=-1-5i
If z = 5I / 1-2i (I is an imaginary unit), then the conjugate complex number of Z is
