To determine

To find: The factorial expression.

Answer to Problem 14AYU

$\frac{12!}{10!}=132$

Explanation of Solution

Given:

$\frac{12!}{10!}$

Calculation:

Using the formula,

$n!=n\left(n-1\right)\left(n-2\right)\dots \dots \dots .3.2.1$ when $n\ge 2$.

We have,

$\frac{12!}{10!}=\frac{12*11*10*9*8*7*6*5*4*3*2*1}{10*9*8*7*6*5*4*3*2*1}=132$
