How many numbers between 1 and 1000 are divisible by 3? How many 4-digit multiples of 5 are there? How many 3-digit numbers can be written using the digits 0,2,2,4, and 6? How many perfect numbers are there? What is the value of the digit 3 in the number 3,725.89?
In this article we consider a number-theoretic enumeration problem associated with primes and Fibonacci numbers. An asymptotic result is obtained for the number of primes occurring between consecutive Fibonacci numbers. We also discuss the limitations of our result....
对于两个数之和为奇数,一个必为奇数,另一个必为偶数,因为所有奇数都是N为整数的2n+1形式,而所有偶数的形式都是2m,其中M是整数.2n+1+2m=2m+2n+1=2(m+n)+1和m+n是整数,因为m和n都是整数.唯一的偶数是2所以我们唯一的组合可能是2和9999.但是,9999可以被3清楚地整除,所以10001可以写为两个素数之和的...

10001表示成两个素数的和 的方式有多少种？
Euler's Totient Functionis denoted by the Greek letter phi, and is defined as follows: phi(N) = how many numbers between 1 and N - 1 which are relatively prime to N. Thus: Here is the same definition expressed as C code: phi = 1; ...

解析 A 有多少种方式将47写成两个质数之和? 47要写成两个整数的和,一个必须是奇数,另一个必须是偶数. 只有一个偶数质数,即2,所以其中一个数必须是2,而另一个数必须是45. 然而,45不是质数,所以没有办法把47写成两个质数的和. 故选A.反馈 收藏 ...
