_____________
8! × 3!
[tex] \sf= ( 8 × 7 × 6 × 6 × 4 × 3 × 2 × 1 ) × ( 3 × 2 × 1 )[/tex]
= 40.320 × 6
= 241.920
[tex]\small{ 8! \times 3 ! }[/tex]
[tex] \small{ = (8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1) \times 3 ! }[/tex]
[tex]\small{ = (56 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1) \times 3 ! }[/tex]
[tex] = \small{ (336 \times 5 \times 4 \times 3 \times 2 \times 1) \times 3 ! }[/tex]
[tex]= \small{ (1.680 \times 4 \times 3 \times 2 \times 1) \times 3 ! }[/tex]
[tex]= \small{ (6.720\times 3 \times 2 \times 1) \times 3 ! }[/tex]
[tex]= \small{ (20.160 \times 2 \times 1) \times 3 ! }[/tex]
[tex]= \small{ (40.320 \times 1) \times 3 ! }[/tex]
[tex]= \small{ 40.320 \times 3 ! }[/tex]
[tex]= \small{ 40.320 \times (3 \times 2 \times 1)}[/tex]
[tex]= \small{ 40.320 \times (6 \times 1)}[/tex]
[tex] = \small{ 40.320 \times 6}[/tex]
[tex] = \small{241.920}[/tex]
