#12#

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!

#12#

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#
