Question

Simplify 3!/4! Why are there !'s? The answer is .75 right?

Answer 1

Nah,\[3!=3\times2\times1\]\[4!=4 \times3\times2\times 1\]

Answer 2

\[n! = n\times(n -1)\times(n-2)\cdots \times 1\]

Answer 3

Nope. If u ! after a number u call it as factorial.
3!=3*2*1
similarly
4!=4*3*2*1

Answer 4

4! = 4x3x2
3!=3x2

24/6=4

Answer 5

Hmm

Answer 6

I still don't understand it. :c

Answer 7

Do you know that\[3!= 3\times2 \times 1\\ 4! = 4\times3 \times 2\times 1\]And so\[\dfrac{\color{#C00}{3!}}{4!} = \dfrac{\color{#C00}{3\times2\times1}}{4\times3 \times 2\times1}\]

Answer 8

6/24 ?

Answer 9

how do I simplify it more? ;w;

Answer 10

Use a calculator.

But it is pretty clear it is 1/4 or 0.25

Answer 11

The exclamation mark means factorial.

In this case 3! Is (3 x 2 x 1)

If It was let's say, 6! It would be (6 x 5 x 4 x 3 x 2 x 1)

So in your question 3!/4 is 3x2x1 divided by 4 which is 6 divided by 4, which is 0.75 :) glad I could help.

Answer 12

Its 3!/4! not 3!/4.

Answer 13

I still don't understand it. But thanks anyway.

Answer 14

Oh, then it's (3 x 2 x 1) / (4 x 3 x 2 x 1)

Which is 6 / 24, meaning the answer is 0.25? :)

Answer 15

Yes.

Btw,What happened to your other account?
