Answer 1

`n!=1\cdot2\cdot3\cdot...\cdot n\\\\6!=1\cdot2\cdot3\cdot4\cdot5\cdot6=720\\\\Answer:\ \boxed{D.\ 720}`

Answer 2

Answer: D.

720

Explanation:

We know that the value of n factorial or n! is given by :-

`n!=n*(n-1)*(n-2)*(n-3)*...........................*1`

We are given to find the value of 6! (or 6 factorial )

Using the above formula , the value of 6! is given by :-

`6!=6*(6-1)*(6-2)*(6-3)**(6-4)*(6-5)\\\\\Rightarrow\ 6!=6*5*4*3*2*1\\\\\Rightarrow\ 6!=720`

Therefore , the value of 6! = 720
