Question 325927: I am not sure what type of problem this is, can anyone help me with it? I don't understand what it is asking me. Compute: 200!/198! Any help would be appreciated! Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! The symbol ! means factorial.
We multiply in a downward direction.
200! = 200 x 199 x 198...all the way down to x 1 for the numerator.
198! = 198 x 197 x 196...all the way down to x 1 for the numerator.
As you can see, 198 down to 1 for the top and bottom of your fraction will cancel out leaving us with (200 x 199)/1.
We can use a calculator.
200!/198! = (200 x 199)/1 = 39,800
