that would be 215, so no. it is divisible by 5, so that means it is not prime.
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
22 + 3 = 7 Since 2 is the only even prime number, this is the only number for which this holds true.
The number 27 has a cube root of 3, which is 2 (the smallest prime) plus 1.
x = 2 : 2 and 3 are both primes.
648 is not prime. 648 = 2 * 2 * 2 * 3 * 3 * 3 * 3
216 is not prime. 216 = 2 * 2 * 2 * 3 * 3 * 3
2 + 3 = 5 Two plus any odd prime number is odd.
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
144 is not prime. 144 = 2 * 2 * 2 * 2 * 3 * 3
2 x 3 x 5 + 1 = 31
No. The lowest prime number is 2.
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
