What is prime number plus prime number?
It is may be prime only if one term is 2. for example: 3+2=5But one term may be 2 and the result composite: 7+2=9=3*3
Student conjecture that if x is a prime number then x plus 1 is not prime. Which of the following answer is a counterexample?
x = 2 : 2 and 3 are both primes.
What is the counterexample of the sum of 2 different prime numbers is even?
2 + 3 = 5 Two plus any odd prime number is odd.
2 and 3 can consecutive whole number prime number?
Yes, 2 and 3 are consecutive prime numbers.
Is 9x2 plus 48xy plus 64y2 prime?
9x2 + 48xy + 64y2 = (3x + 8y)2. Since it is a squared number cannot be a prime. We can say that as a perfect square number, it is formed by the sum of 1 and some prime numbers (excluded 2), i.e 1 + 3 + 5 + 7 + 11 + ... n, where n is a prime.
What is prime number plus prime number?
It is may be prime only if one term is 2. for example: 3+2=5But one term may be 2 and the result composite: 7+2=9=3*3
What prime number squared plus 3 gives an odd number?
22 + 3 = 7 Since 2 is the only even prime number, this is the only number for which this holds true.
What number's cube root is 1 more then the smallest prime?
The number 27 has a cube root of 3, which is 2 (the smallest prime) plus 1.
Student conjecture that if x is a prime number then x plus 1 is not prime. Which of the following answer is a counterexample?
x = 2 : 2 and 3 are both primes.
What is the counterexample of the sum of 2 different prime numbers is even?
2 + 3 = 5 Two plus any odd prime number is odd.
2 times 3 times 5 plus 1 is what prime number?
2 x 3 x 5 + 1 = 31
Why is it when you multiply two prime numbers you get a number with three or four factors?
If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.
To what prime number can you add 3 and get a sum that is a prime number?
2. 2 + 3 = 5 Or if you mean like add 3 to the prime number, then add that to the prime? 2 still works!! 2: 2 + 3 = 5. 5 + 2 = 7
Are 2 and 3 a prime factor of 24?
Yes 2 and 3 are prime factors of 24 because; 2 is a prime number and fits in to 24 3 is a prime number and fits into 24
2 and 3 can consecutive whole number prime number?
Yes, 2 and 3 are consecutive prime numbers.
Is 3 the lowest prime number?
No. The lowest prime number is 2.
What are the prime factors of 78?
The prime factors of 78 are 2, 3, and 13. To find the prime factors of a number, you can start by dividing the number by the smallest prime number, which is 2. If the number is divisible by 2, continue dividing by 2 until you reach a point where it is no longer divisible by 2. Then, move on to the next prime number, which is 3. Repeat the process until you have factored the number completely into its prime factors.
