AI Thread Summary
The discussion centers on proving whether the expression (n!)! / (n!)^(n-1)! is an integer for natural numbers n. Participants note that the question lacks clarity regarding what specifically needs to be proven. It is mentioned that this inquiry is not new and resembles a previously posed question with different values. There is a consensus that the goal is to establish the integer nature of the expression. The conversation emphasizes the need for a more detailed formulation of the problem.

Prove by permutations or otherwise $\displaystyle \frac{\left(n!\right)!}{\left(n!\right)^{(n-1)!}}$, where $n\in \mathbb{N}$

Your question is not complete. What do you need to prove?
 
This is not a new question. it is same as previous question with diffeent value

I think you mean it to be integer

this is same as previous solution with m= (n-1)! http://mathhelpboards.com/challenge-questions-puzzles-28/integer-quantity-12418.html
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
