Explicação passo a passo:

$\mathsf{z = \left(\dfrac{1 + 3i}{2 - i}\right)}$

$\mathsf{\overline{\rm z} = \left(\dfrac{1 + 3i}{2 - i}\right).\left(\dfrac{2 + i}{2 + i}\right)}$

$\mathsf{\overline{\rm z} = \dfrac{2 + i + 6i + 3(i)^2}{4 - (i)^2}}$

$\mathsf{\overline{\rm z} = \dfrac{2 +7i + 3(-1)}{4 - (-1)}}$

$\mathsf{\overline{\rm z} = \dfrac{2 +7i - 3}{4 + 1}}$

$\boxed{\boxed{\mathsf{\overline{\rm z} = \dfrac{-1+7i}{5}}}}$
