Because it is a product of real numbers. And the set of real numbers is closed under multiplication.

How many zeros are possible factorial 10 to the power factorial 10?

To calculate the number of zeros in a factorial number, we need to determine the number of factors of 5 in the factorial. In this case, we are looking at 10 to the power of 10 factorial. The number of factors of 5 in 10! is 2 (from 5 and 10). Therefore, the number of zeros in 10 to the power of 10 factorial would be 2.


How many diagonals do hexagons have?

The number of diagonals in an n-sided polygon is given by nC2 - n (where n is the number of sides of the polygon) or in the expanded form: factorial (n) _______________________ {factorial (2) * factorial (n-2)} substituting (n = 6) for a hexagon we get the number of diagonals as 9. Similarly, substituting (n=5) for a pentagon we get the number of diagonals as 5.


Write a recursive procedure to compute the factorial of a number?

What is the time complexity, in terms of Big O notation, for calculating the factorial of a number?

The time complexity for calculating the factorial of a number is O(n), where n is the number for which the factorial is being calculated.


What does an exclamation mark after a number mean?

Mathematically it represents a factorial of that number. A factorial is when you take each number up to value and multiply them. So factorial 5 is 1 x 2 x 3 x 4 x 5. Factorial 11 is 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11. This is often written with the number you are getting the factorial for, followed by an exclamation mark.

What is 9! simplified?

9! (9 factorial) is equal to 362,880. Factorial is the product of all positive integers up to a given number. In this case, 9! is calculated as 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1, which equals 362,880.
