Hi,
I have a question about factorials that I'm hoping someone can help me with.
I know that the factorial n! means the product of the integers from 1 to n, for example if I have 4! then this is equal to 4 x 3 x 2 x 1 = 24, but I have an equation which contains the term:
k(n-1)!
I am not sure how to interpret this...for instance, if we assume that k=4 and n=8, does this give:
4(8-1)!
= 4 x 7!
= 4 x 5,040
= 20,160
Or does it give:
4(8-1)!
=4 x 7!
=28!
=3.0489 x 10^29
I'm guessing it's the first one but am not sure...can someone confirm or provide the correct answer please?
Many Thanks
