Is 61 A Prime Number
Write all pairs of prime numbers a and b with a total of 61 (a, b) ... (CONTINUE) Please help?
First, know that the sum of two numbers is the same, the sum of two odd numbers is equal, and the sum of equal and odd numbers is odd.
In this case, for two numbers a and b that add up to 61, one of them is equal to one or B and the other is odd because 61 is odd.
The only equivalent is number 2. Since you know that one of the two primes is equal, 2 is the first number. The second number is only 612 = 59 (which, if you check, is a prime number).
So the answer is:
Ba =
59 2 = 57

All basic pairs a and b, whose sum is 61, are written in (a, b), where b is greater than a. What is the sum of all the unique Ba sects?
First, know that the sum of two even numbers is even, the sum of two odd numbers is even, and the sum of one even and odd number is odd.
In this case, for two numbers a and b which add up to 61, one of the two is equal to a or b and the other is odd, because 61 is odd.
The only prime number is 2. Since you know that one of the two primes is a pair, 2 is the first number. The second number is just 612 = 59 (which, if you check, is a prime number).
So the answer is:
ba =
59 2 = 57
