A prime number is a number which can only be divided by one or the number itself. The number 22 can be divided by one, two, eleven and 22. Thus, it is NOT a prime number
That would be 29.
the prime factors of sum of 121 is 112 and 22
No, as this represents the sum of two 11th powers. There is a factorization of x^11+y^11; however it is lengthy. The sum is 10^22+1^22.
The only factors of -9 are -1 & 9, 3 & -3 and 1 & -9. None of these sum to 22.
19 and 3; 17 and 5.
If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)
Two prime numbers such that their sum is 22:- i) 19 and 3 ii) 17 and 5 If we don't consider the prime numbers to be distinct then 11 and 11 is also a solution.
Not true. 12 + 22 = 1 + 4 = 5 which is a prime. Or 42 + 52 = 16 + 25 = 41, also a prime.
22 + 32 = 13

13
22 is a composite number because it has more than two factors whereas a prime number has only two factors which are itself and one.
The only factors of -9 are -1 & 9, 3 & -3 and 1 & -9. None of these sum to 22.
