What is the factorial of 1.5 Factorial of 1.5: 1.5? ~ e ~ okay, off?


Generally, the factorial is defined in the range of natural number, and the decimal has no factorial, such as 0.5, 0.65, 0.777! Is wrong. However, sometimes we define gamma function as non integer factorial, because when x is a positive integer n, the value of gamma function is n-1 factorial



What is the factorial of 5?


5*4*3*2*1=120



Factorial 5!


Double factorial. 5! = 5x3x1 = 15



2. How do you get to 24:00 on 13, 4, 8?
No one understands!


A:
2×13-8÷4=24



Using the idea of recursion, we can calculate the sum of factorials of prime numbers in [1100], that is, 2! + 3! + 5! + 7! + +89!+97!.
1. Please print out the sum of all prime numbers and prime factorial in the interval line by line


#include "stdio.h"#include "math.h"double jc(double d){if(d>1)return d*jc(d-1);elsereturn 1;}double sushu(double d,double s){int i...



The sum of five prime numbers is 2010. How much is the smallest prime number?


If all five prime numbers are odd, then the sum of the five prime numbers is odd
Now the sum is even, so there must be an even number in the five prime numbers
2 is even and the smallest prime
So the smallest is 2



The sum of a prime number and its 8 times is 45. What is the prime number


45÷(1+8)=45÷9=5
A: the prime number is 5



If a prime number is prime after adding 6, 8, 12 and 14, then the prime number is______ .


Let this prime number be x, divide X by 5, and divide the remainder into the following five cases: when x = 5K + 1, then x + 14 = 5 (K + 3) is a composite number, when x = 5K + 2, then x + 8 = 5 (K + 2) is a composite number, when x = 5K + 3, then x + 12 = 5 (K + 3) is a composite number, when x = 5K + 4, then x + 6 = 5 (K + 2) is a composite number, so only x = 5K and K is 1, that is x = 5



What is the factorial of n square
1^2+...+n^2=?


1^2+...+n^2=n(n+1)(2n+1)/6



Prove that N times (n + 1) can not be a complete square number (n is any number)


Because (n + 1) ^ 2 = n ^ 2 + 2n + 1 = n ^ 2 + N + N + 1
So n (n + 1) = n ^ 2 + NN ^ 2
So n ^ 2
