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
Here's a simple Java program to find the factorial of a given number using a recursive method: import java.util.Scanner; public class Factorial { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter a number: "); int number = scanner.nextInt(); System.out.println("Factorial of " + number + " is " + factorial(number)); } static int factorial(int n) { return (n == 0) ? 1 : n * factorial(n - 1); } } This program prompts the user for a number and calculates its factorial recursively.
To write a program that calculates the factorial of a number in PHP, you can use a recursive function or an iterative approach. Here’s a simple example using a loop: function factorial($n) { $result = 1; for ($i = 2; $i <= $n; $i++) { $result *= $i; } return $result; } echo factorial(5); // Outputs: 120 This code defines a function that multiplies numbers from 2 up to the given number $n to compute the factorial.
(x-8)(x+8) = x2-64
8! means 8*7*6*5*4*3*2*1=40,320
720
That's not the factorial of any number. For a start, the factorial of any number greater than or equal to 2 is even, because of the factor 2. The factorial of any number greater or equal to five ends with 0. Another answer: I suspect the questioner meant to ask how to write 8*7*6*5*4*3*2*1 as a factorial. If so, then the answer is "8!"
8!
40320
3! = 3×2×1 = 6
Regular expression is built in and the regular definition has to build from regular expression........

The regular expression for an integer is: -?d

When a factorial is in parentheses, it typically indicates that the entire expression within the parentheses should be evaluated first before applying the factorial operation. For example, (n!) means to first calculate the value of n and then take the factorial of that value. This notation helps clarify the order of operations in mathematical expressions.
9 factorial = 9! = (9*8*7*6*5*4*3*2*1) = 362880
