or about 4.0239 x 102567
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
For integers greater than 1 the product down to 1 is called factorial, indicated mathematically as N! wher N is the highest integer For example 5! = 5 factorial = 5x4x3x2x1 = 120
7 factorial means 7x6x5x4x3x2x1 which can be rewritten as 7x(3x2)x5x(2x2)x3x2x1 when 6 and 4 are factored. Notice the repeating factors are (3x3)x(2x2)x(2x2) = (3x2x2)x(3x2x2) = 12 squared = 144
