Answer:
begin mathsize 16px style straight D equals open vertical bar table row cell straight a subscript 1 straight l subscript 1 plus straight b subscript 1 straight m subscript 1 end cell cell straight a subscript 1 straight l subscript 2 plus straight b subscript 1 straight m subscript 2 end cell cell straight a subscript 1 straight l subscript 3 plus straight b subscript 1 straight m subscript 3 end cell row cell straight a subscript 2 straight l subscript 1 plus straight b subscript 2 straight m subscript 1 end cell cell straight a subscript 2 straight l subscript 2 plus straight b subscript 2 straight m subscript 2 end cell cell straight a subscript 2 straight l subscript 3 plus straight b subscript 2 straight m subscript 3 end cell row cell straight a subscript 3 straight l subscript 1 plus straight b subscript 3 straight m subscript 1 end cell cell straight a subscript 3 straight l subscript 2 plus straight b subscript 3 straight m subscript 2 end cell cell straight a subscript 3 straight l subscript 3 plus straight b subscript 3 straight m subscript 3 end cell end table close vertical bar
straight D equals open vertical bar table row cell straight a subscript 1 straight l subscript 1 end cell cell straight a subscript 1 straight l subscript 2 end cell cell straight a subscript 1 straight l subscript 3 end cell row cell straight a subscript 2 straight l subscript 1 end cell cell straight a subscript 2 straight l subscript 2 end cell cell straight a subscript 2 straight l subscript 3 end cell row cell straight a subscript 3 straight l subscript 1 plus end cell cell straight a subscript 3 straight l subscript 2 end cell cell straight a subscript 3 straight l subscript 3 end cell end table close vertical bar plus open vertical bar table row cell straight b subscript 1 straight m subscript 1 end cell cell straight b subscript 1 straight m subscript 2 end cell cell straight b subscript 1 straight m subscript 3 end cell row cell straight b subscript 2 straight m subscript 1 end cell cell straight b subscript 2 straight m subscript 2 end cell cell straight b subscript 2 straight m subscript 3 end cell row cell straight b subscript 3 straight m subscript 1 end cell cell straight b subscript 3 straight m subscript 2 end cell cell straight b subscript 3 straight m subscript 3 end cell end table close vertical bar equals straight D subscript 1 plus straight D subscript 2
Consider comma space
straight D subscript 1 equals open vertical bar table row cell straight a subscript 1 straight l subscript 1 end cell cell straight a subscript 1 straight l subscript 2 end cell cell straight a subscript 1 straight l subscript 3 end cell row cell straight a subscript 2 straight l subscript 1 end cell cell straight a subscript 2 straight l subscript 2 end cell cell straight a subscript 2 straight l subscript 3 end cell row cell straight a subscript 3 straight l subscript 1 plus end cell cell straight a subscript 3 straight l subscript 2 end cell cell straight a subscript 3 straight l subscript 3 end cell end table close vertical bar
straight D subscript 1 equals straight a subscript 1 straight a subscript 2 straight a subscript 3 open vertical bar table row cell straight l subscript 1 end cell cell straight l subscript 2 end cell cell straight l subscript 3 end cell row cell straight l subscript 1 end cell cell straight l subscript 2 end cell cell straight l subscript 3 end cell row cell straight l subscript 1 plus end cell cell straight l subscript 2 end cell cell straight l subscript 3 end cell end table close vertical bar equals 0
Similarly space you space can space solve space for space straight D subscript 2.
straight D equals 0 plus 0 equals 0 end style
