Since (k+1)! = (k+1)k! = (k+1)k(k-1)!,

Hi,

The answer according to Maple is .

Is it wrong? - Nov 1st 2013, 05:08 PMemakarovRe: Simplifying Expression with Like Denominators and Factorials

Example:

Edit: In other words, they already had like denominators, but

So, if you multiply by , you don't get . - Nov 1st 2013, 08:47 PMProve ItRe: Simplifying Expression with Like Denominators and Factorials
