at the numerator n+1 by n+1-1 = n subtract one again n-1 one more time n-1-1 = n -2 right you need to keep subtracting by one ntill you get anything to divide with at the denominator
Nnesha
  • Nnesha
that's a calculator if you want step then YES you have to pay :D
anonymous
  • anonymous
Ya I just noticed that. And so I just need to subtract 1 until I get n-5?
Nnesha
  • Nnesha
if you do simple question like 5! \[5 \times 4 \times 3 \times 2 \times 1\] here you are subtracting one right so same method for that one too
Nnesha
  • Nnesha
well for this question subtract one 't the denominator and t the numerator
anonymous
  • anonymous
So triciaal did it right then. You are suppose to keep multiplying both the numerator and denominator so you can get rid of like terms?
Nnesha
  • Nnesha
yes right you need *LIke terms * to cancel out
anonymous
  • anonymous
So the answer is 3(n+1)/5?
anonymous
  • anonymous
Ohh okay sorry about that.. @200205650

  • anonymous
That's fine @AnonymousHelper

\[\frac{ 3(n+1)! }{ 5n!} = \frac{ 3(n+1\color{reD}{-1}) (n\color{ReD}{-1})(n-1\color{reD}{-1}) }{ 5(n\color{ReD}{-1})(n-1\color{reD}{-1}) }\]

yes that's right
