8! means 8*7*6*5*4*3*2*1=40,320
3! = 3×2×1 = 6
Not sure about a square route, but the square root of 654321 is 808.901 (to 3 dp).
How do you write an expression
It is 4060.
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! means 8*7*6*5*4*3*2*1=40,320

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.
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.
