If ,

$\bold{z=-3+5i }$

so,conjugate of z

$\overline{ z }$ =
$\bold{-3-5i }$

Because, in argand plane
$\overline{ z }$ is the reflection of z in x-axis.

so,

According to the question,

z
$\overline{z}$ =(-3+5i)(-3-5i)

$\bold{(-3)^2-(5i)^2 }$

$\bold{9-25(-1) }$

$\bold{ 9+25 }$

$\bold{ 34 }$
