we will substitute the values of n in given expression
when substituting n=1 we get in =
when n=2 we get
when n =3 we get ;3 factorial that is 3! = 3 *2*1 = 6
when n=4 we get ;4! = 4*3*2*1 = 24
Note: factorial means the product of the terms getting multiplied till 1
suppose n! will be equal to n(n-1)(n-2)(n-3).......1
