Question

How to solve for n: nP5=14(nP4)
and nP3=17(nP2)
permutations?

Answer 1

I need to ask two questions before beginning this problem.

1) Do you understand this: 5! = 5*4! ?

2) Do you understand this: (n - 4)! = (n -4) * (n - 5)! ?

Answer 2

Actually, I understand how to do the problems now. Thanks though!

Answer 3

Alrighty, then. I asked the questions because those relationships are needed to solve the problems.
