Question

How do you simplify `3!2!`?

Answer 1

`12`

Explanation:

Recall that

`3! =3xx2xx1` and

`2! =2xx1`

Remember, factorial means we take that number and multiply it by one less than the previous number.

Putting it together, we get

`3*2*1*2*1`

`=4*3=12`

Hope this helps!

Answer 2

`12`

Explanation:

Given: `3!2!`.

`=3!*2!`

The factorial definition states that for any whole number `n`, `n!` is defined as:

`n!\=n(n-1)(n-2)...*4*3*2*1`

So, we get:

`3!*2!`

`=3*2*1*2!`

`=3*2*1*2*1`

`=6*1*2*1`

`=12*1*1`

`=12`
