Question 40453: please help me with this
in how many ways can you arrange eight books on a shelf?
and for my knowledge how would you figure out a question like this?
Answer by Nate(3500)   (Show Source):
You can put this solution on YOUR website! P(8,8) = 8!/0! = 40,320
You would use permutations because your arrangement does matter.
Also, look at this:
How many books can be first? .... answer: 8
How many books can be second? .... answer: 7
How many books can be third? .... answer: 6
How many books can be fourth? .... answer: 5
How many books can be fifth? .... answer: 4
How many books can be sixth? .... answer: 3
How many books can be seventh? .... answer: 2
How many books can be eigth? .... answer: 1
Find the product of the whole row .... 8*7*6*5*4*3*2*1 = 40,320
