Question 1070315: I'm still looking for an answer to this question...
"If the number of permutations of n objects taken r at a time is 6^0 times the number of combinations of n objects taken r at a time, determine the value of r "
I do realize that 6^0 = 1, the question is stated exactly the way it was given to me.
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! Theorem: The number of permutations of n objects taken r at a time is:
P_n,r = n(n-1)(n-2)...(n-r+1) and we can rewrite it like this:
P_n,r = n!/(n-r)!
:
In this problem P_n,r = 6^0 = 1. Good luck figuring out the value of r.
