16! over4! times 12!=

Question

kainui · Answer

Remember that factorial just means every number counting up to that one multiplied by it. So...

4!=1*2*3*4

Expand it out and see for yourself.

anonymous · Answer

both

kainui · Answer

Just apply what you just learned, you're right.

anonymous · Answer

well, 16! is quite a large number

kainui · Answer

It's not that large to write out on paper.

anonymous · Answer

Is it (16!/4!)*12! or (16!)/(4!*12)

kainui · Answer

There's only one way to learn math in my book, and that's by doing. Expanding out the factorial will give firsthand experience with what's going on and he won't have to keep asking us questions. =D

anonymous · Answer

2.092278989x10^13 is large

anonymous · Answer

(16!)/(4!*12)

anonymous · Answer

expand 16! upto 4! thn cncl out 4! over 4! and mutaltiply remaining numbers and thb find 12! and do simple calculation

anonymous · Answer

A.	.0238
	B.	1,820
	C.	2,380

those are the choices

anonymous · Answer

since x! = 1*2*3*4..*x:
16! = 12! *13*14*15*16

(12! *13*14*15*16) / (4!*12!) = (13*14*15*16)/(4!) = (43680/(4!)
=43680/(1*2*3*4) = 43680/24 = 1820

kainui · Answer

@uj1024 If you expand it out without simplifying you will see that most of the terms cancel out. It's not that crazy...

anonymous · Answer

Since since x! = 1*2*3*4..*x:

4! = 1*2*3*4
4! = 2!*3*4
4! = 3!*4

x! is just a way to represent multiplying 1 to x all together (whole numbers only).
