Question

4!(7 – 4)!
I need help on how to figure this problem out step by step.

Answer 1

When you have an exclamation point at the end of the number like that, you're multiplying that number by every whole number that is less than it until you hit 1.


So 6! for example is 6! = 6*5*4*3*2*1 = 720

Answer 2

So what is 4!

Answer 3

So 4! would be 24 right?

Answer 4

you got it

Answer 5

Now to find (7-4)!, you first evaluate what you see in the parenthesis. So 7-4 = 3


So

(7-4)!

becomes

3!

Answer 6

Now what is 3!

Answer 7

3! would be 6.

Answer 8

good

Answer 9

oh wait I misread

Answer 10

so

4!(7-4)!

becomes

4!3!

which becomes


24*6


and that turns into


144


Therefore, 4!(7-4)! = 144

Answer 11

oh okay I got it now! Thank you SO much :DDD

Answer 12

you're welcome :)
