Answers:

.0238

23,800

2,380

Some number less than 1

Answer 1

17! = 17 x16 x15x...x1
but there is a button on your calculator that will do this also, so ust type 1in 17 and hit the factoria button ( which is normally an n followed by an exclamation mark)

Answer 2

Alternativey, you coud note that 17! = 17 x 16 x15 x 14 x 13 x12...etc
but 13! aso has 13x 12 ...etc so these would cancel each other to leave:
17 x 16 x 15 x 14/3!

Answer 3

This is so confusing..

Answer 4

what is?

Answer 5

this whole thing.

Answer 6

these are known as factorials, in simpe terms it means if I have 17! (which you pronounce as "17 factorial") it means multiply 17 x 16 x 15 etc all the wway down to 1. Nothing more to it. Its a shorthand way of saying this.

Answer 7

ok but i cant find my final answer.

Answer 8

17 x16 x15 x14 = 57120
Now to divide by 4! = 4 x 3 x 2 x 1 = 24
so we get 57120 /24 = 2380
