Question 1178176: What is the answer in the following?
•P(n,n-1)=6
•P(16,4)=208•P(n,2)
Answer by greenestamps(13198) (Show Source): You can put this solution on YOUR website!
•P(n,n-1)=6
P(n,n-1) has the same value as P(n,n), which is n!:
P(n,n-1) = n(n-1)...(3)(2) = n(n-1)...(3)(2)(1) = n!
So the first problem is
n! = 6
Trivially, the answer is n=3.
•P(16,4)=208•P(n,2)
Clearly n=15.
