# How do you evaluate (10!)/(4!)?

May 7, 2017

(10!)/(4!) = 151,200

#### Explanation:

By hand you need to know that 10! = 10 * 9 * 8 * 7 * 6 * 5 * 4!

So 10! = (10 * 9 * 8 * 7 * 6 * 5 * cancel(4!))/(cancel(4!)) = 10 * 9 * 8 * 7 * 6 * 5 = 151,200

A TI graphing calculator can do factorials:

$10 \text{ MATH > PRB " 4 -: 4 " MATH > PRB } 4$ ENTER

10! "/" 4! " " 151,200
