No, it cannot be done. As 23 is odd, two numbers used would have to be one odd and one even. As 2 is the only even prime number and 21 + 2 equals 23, but 21 is not a prime number, it cannot be done.
as 132 is an even number at least one of the two numbers must also be even 12 + 11 = 23 12 x 11 = 132
Only 1 and 23 (23 is a prime number).
An integer is a whole number. For instance, 1, 2, 3... There is no decimal part. So 23 is an integer. A rational number is a number that can be written as a/b. 23 can be written as 23/1, so 23 is a rational number. Thus, 23 is BOTH an integer and a rational number.
23 is prime.
23 is an odd number.
No
If the number is 23,512, the number is even. If the number is 23.512 the number is odd.
No, there is an infinite number of primes containing an even number.
23 is an odd number.
8
23 is odd. A sum of two even numbers never makes an odd number. Likewise, no sum of two odd numbers makes an odd number. 23 can only be made by adding an odd and an even number.
21 or 22
No, it cannot be done. As 23 is odd, two numbers used would have to be one odd and one even. As 2 is the only even prime number and 21 + 2 equals 23, but 21 is not a prime number, it cannot be done.
No. The sum as well as product of two even numbers can only be an even number.
23 is a prime number so there is no prime factorization. Some consider it to be acceptable to write 1 X 23 in order to show the number is prime, even though 1 is not a prime or composite number.23 is already prime.
23 is a prime number. 26 is even, and the only even prime is 2. The prime factors of 26 are 2 & 13.
