Answer:
B. 5040
Step-by-step explanation:
We want to find the value of [tex]7![/tex].
We read [tex]7![/tex] as ''seven factorial''
By definition, [tex]n!=n(n-1)(n-2)...3\cdot2\cdot1[/tex]
We need to find the product of all the positive integers less than or equal to the given number.
This implies that:
[tex]7!=7\times 6\times 5\times 4\times 3\times 2\times 1[/tex]
[tex]7!=5040[/tex]
