Why does the prime formula not give us two twin primes?
There is no known prime formula to identify all primes. There are some formulae that work only for some classes of primes. Mathematicians have
Will you get the same number of factors if you multiply a prime number and itself?
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
One number is 3 times another number. If the sum of the reciprocals of the number is 1 divided by 6. What are the two numbers?
12 and 18
There are two numbers with the LCM of 72 the smaller number is nine the GCF of the two numbers is three and their sum is between 30 and 40 what is the larger number?
35 i do not really no
Cbse class VIII math solved papers?
Expression as square of number of sum two or more
The sum of two odd number is?
The sum of two odd primes is always an even answer or number.
What is the smallest prime number that is the sum of two primes?
5
What even number is not the sum of two primes?
16
Write the number 18 as the sum of two primes?
1 + 17 = 18 5 + 13 = 18 7 + 11 = 18
What is the only prime number that is the sum and difference of two primes?
5
What number is neither prime or the sum of two distinct primes?
One.
Express 46 and 38 as the sum of two odd primes?
To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
How does the number 30 fit the goldbach's conjecture?
Goldbach's conjecture says that every even number greater than two can be expressed as the sum of 2 primes. If 30 could not be expressed as the sum of two primes, then this would disprove the conjecture. As it is, 30 can be expressed as the sum of two primes. You can express it as 11+19. Thus, Goldbach's conjecture holds in this case.
What prime numbers add up to 92?
Write 92 as the sum of two primes
Prove that if every even natural number greater than 2 is the sum of two primes then every odd natural number greater than 5 is the sum of three primes?
Given an arbitrary odd natural number greater than five, x, let y = x - 3, then y is an even number greater than 2. By assumption we have that y is the sum of two primes, say y1 and y2, but then x = y1 + y2 + 3 (which is the sum of three primes).
Is the sum of two primes even?
Yes. all prime numbers are odd numbers so the sum of any two will be an even number.
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
