What is the value of n if 4!+5=n!3!
[4 x 3 x 2 x 1] + 5 = n! x [3 x 2 x 1]
29 =n! x 6
n! =29 /6
n! =4.8333..........
n =3.82431 This is called the "Gamma function"
No it isn't, the Gamma Function relationship
Gamma (n+1) = n!
is valid only when n is a positive integer or zero.
I think that there is probably a typo in the question, the 5 should be 5! .
