Choose 3 then 2 then 1; 3*2*1 = 6 ways.
The answer to this one is 24. You can do this mathematically by 4*3*2*1.
There are 40320 ways.
The answer would be 7! or (7*6*5*4*3*2*1)=5040
7*6*5*4*3*2*1= 5040 different ways
8!=8*7*6*5*4*3*2*1=40320 ways
5 books can be lined up on a shelf in (5 x 4 x 3 x 2 x 1) = 120 different sequences.
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 = 40,320 ways !
You can arrange 4 in 2 ways 1x4 and 2x2.
