(1)
{{{ 5 / ( 1 - 2i ) }}}
{{{ (( 1 + 2i ) / ( 1 + 2i )) *( 5 / ( 1 - 2i )) }}}
{{{ ( 1 + 2i ) *( 5 / (( 1 + 2i )*( 1 - 2i ))) }}}
{{{ ( 1 + 2i )*( 5 / ( 1 - 4*(-1)  )) }}}
{{{ ( 1 + 2i )*( 5 / ( 1 + 4 )) }}}
{{{ ( 1 + 2i )*( 5/5 ) }}}
{{{ 1 + 2i }}}
----------------
(2)
{{{ ( 2 + 3i )/( 2 - 3i ) }}}
{{{ (( 2 + 3i )/( 2 + 3i )) * (( 2 + 3i ) / ( 2 - 3i )) }}}
{{{ ( 2 + 3i )^2 / ( ( 2 + 3i )*( 2 - 3i ) ) }}}
{{{ ( 2 + 3i )^2 / ( 4 - 9*(-1) ) }}}
{{{ ( 4 + 12i + 9*(-1) ) / ( 4 + 9 ) }}}
{{{ ( -5 + 12i ) / 13 }}}
{{{ -5/13 + (12/13)*i }}}
