$12$

#### 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

$3 \cdot 2 \cdot 1 \cdot 2 \cdot 1$

$= 4 \cdot 3 = 12$

Hope this helps!

#### 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!

$= 3 \cdot 2 \cdot 1 \cdot 2 \cdot 1$

$= 6 \cdot 1 \cdot 2 \cdot 1$

$= 12 \cdot 1 \cdot 1$

$= 12$
