Answer 2

Answer: 72

Explanation:

By definition, it is important to know that the factorial of a non-negative integer "n" is the product of all positive integers less than or equal to "n". This is expressed with an exclamation symbol (!):

`n!`

Then, the rule for this is the following:

`n! = n *(n-1)!`

Therefore, knowing this, you can evalute
`(9!)/(7!)` as following:

`(9*8*7*6*5*4*3*2*1)/(7*6*5*4*3*2*1)=(362,880)/(5,040)=72`
