Hello there!
The formula is
N! = n(n -1)(n - 2)
Now all we have to do is replace N by 4
N! = 4(4-1)(4-2)
= (4)(3)(4-2)
= (12)(2)
= 24
Here you go, the answer is : 24
I hope this answer help! Good luck with your studies.
When you multiply two fractions together, multiply the two top numbers and then multiply the two bottom numbers.
5/12 x 1/3 = (5x1) / (12x3) = 5/36
3 1/2r=28
7/2r=28
r=(28/1)(2/7)
r=8
True!
4(0) -1 = -1
2(0) +7 = 7
