SOLUTION: Use the definition
(n)
(r) = n!/ r!(n-r)! to prove that
(n) = (n )
(r) (n - r)
This is from a binomial theorem part of a textbook.
The n and r are in t

Question 939593: Use the definition
(n)
(r) = n!/ r!(n-r)! to prove that
(n) = (n )
(r) (n - r)
This is from a binomial theorem part of a textbook.
The n and r are in the same bracket with the letter n on top of r.
Also (n and n-r) are in the same bracket too with n-r being under n.
Sorry I wasn't sure how to write this question properly on a pc.
Any help on this would be appreciated. Answer by Edwin McCravy(20055) (Show Source):
