Ido not get this. evaluate. simplify your answer as much as possible. 3! 6! /5! 2!

18

Step-by-step explanation:

n! = n * (n-1)!

For example 7!  can be written as 7 * 6!

3! is 3* 2!

6! is 6 * 5!

Cancel out 5!  from the top and bottom . Also cancel out 2! from top and bottom.

3*6= 18

they are simplified

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
