Question

Evaluate 5!/3! HELP ME PLEASE

Answer 1

For this case we have that by definition, the factorial of a number is the product of the "n" consvutive factors from n to 1. The factors are in descending order, that is:

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

Then, we have the following expression:

`\frac {5!} {3!}`

Applying the definition we have:

`\frac {5!} {3!} = \frac {5 * 4 * 3 * 2 * 1} {3 * 2 * 1} = \frac {120} {6} = 20`

ANswer:

20

Answer 2

20

Explanation:

5! = 5*4*3*2*1

3! = 3*2*1

5!/3! = 5*4*3*2*1

----------------

3*2*1

Canceling common factors

= 5*4

= 20
