a. B. C is three prime numbers within 100. How many satisfy a + B = C

If ABC is odd, then a + B = C does not hold
So there's an even number, which is 2
There are
2+3=5
2+5=7
2+11=13
2+17=19
2+29=31
2+41=43
2+59=61
2+71=73

12. ABC is three prime numbers and the product of ABC is five times of the sum of ABC. How much is the sum of a ^ 2 + B ^ 2 + C ^ 2 abc=5(a+b+c) Because a, B, C are all prime numbers, so one of a, B, C is 5, and because the band formula is rotational symmetry, any change of the order of a, B, C does not affect the result Let a = 5 To 5BC = 25 + 5B + 5C Divide both sides by 5 bc=5+b+c bc-b-c+1=6 (b-1)(c-1)=6=1*6=2*3 If it is decomposed into 2 * 3, then B and C are 3 and 4 respectively So (B-1) (C-1) = 1 * 6 Let B-1 = 1 and C-1 = 6 So B = 2, C = 7 a^2+b^2+c^2=5^2+2^2+7^2=78 Why does ABC have a number of 5
