What is 8!/4!? Type your answer WITHOUT any commas. Do NOT type commas.

Question

I need help with this.

Answer 1

8! is simply 8*7*6*5*4*3*2*1

 

and 4! is 4*3*2*1

 

We note that by dividing 8! with 4! since 4*3*2*1 is common to both the denominator and numerator, they cancel out and we are left with 

 

8*7*6*5 which equals 1680

 

Answer 2

= 8(7)(6)(5) = 56(30) = 1680
