Question

Evaluate each expression6! =3! • 2=Then Explain

Answer 1

Given the following expression:

6! =

3! • 2=

We will use the following formula to evaluate the expressions:

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

So, the values of the given expression will be as follows:

`\begin{gathered} 6!=6*5*4*3*2*1=720 \\ 3!*2=3*2*1*2=12 \end{gathered}`

So, the answer will be:

6! = 720

3! • 2= 12
