Reducing Factorials: Is the Answer 1/[2n*2n+1]?

Click For Summary
SUMMARY

The discussion centers on simplifying the expression (2n-1)!/(2n+1)! and confirming that the result is indeed 1/[2n(2n+1)]. Participants clarify that while the answer is correct, it is more visually clear when presented with parentheses. The expression can be rewritten as 1/(2n*2n+1) for better readability, emphasizing the importance of proper notation in mathematical expressions.

The Attempt at a Solution



...2n-2*2n-1
------------ (pretend that's a divider)
...2n-2*2n-1*2n*2n+1

Is the answer 1/[2n*2n+1]?

It sure is.
 
But it would look better with an additional pair of parentheses:
1/[2n(2n+1)]. I would have been inclined to interpret what you have as
1/(2n2+1).
 
Thanks :)
