As we know that the formula of
n!=n(n-1)!
so 8!=8*(8-1)!
=8*7!
=8*7*6!
=8*7*6*5!
=8*7*6*5*4!
=8*7*6*5*4*3!
=8*7*6*5*4*3*2!
=8*7*6*5*4*3*2*1!
=8*7*6*5*4*3*2*1
=40320
so the factorial of the given no. 8 is 40320.

9 x 8! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1So, 9 x 8! = 9! = 362,800
x - 8
It is: 3(n+8)
(x-8)(x+8) = x2-64
Great. A multiple choice question with no choices. Find the expression that equals 8.
