Let’s check out your problem:

Verify the expression: 8(n!)((m3)!(nm3)!)=(m!)((m3)!(mm3)!)\frac{8(n!)}{((m-3)!(n-m-3)!)}=\frac{(m!)}{((m-3)!(m-m-3)!)},

Q. Verify the expression: 8(n!)((m3)!(nm3)!)=(m!)((m3)!(mm3)!)\frac{8(n!)}{((m-3)!(n-m-3)!)}=\frac{(m!)}{((m-3)!(m-m-3)!)},
  1. Simplify First Expression: Simplify the first expression:\newline8(n!)(m3)!(nm3)! \frac{8(n!)}{(m-3)!(n-m-3)!} \newlineHere, n! n! is the factorial of n n , and the denominators are the factorials of m3 m-3 and nm3 n-m-3 respectively.
  2. Simplify Second Expression: Simplify the second expression:\newline(m!)(m3)!(mm3)! \frac{(m!)}{(m-3)!(m-m-3)!} \newlineNotice that mm3 m-m-3 simplifies to 3 -3 , which is not valid for factorial operations as factorials are defined only for non-negative integers.
