Given that AB is prime and 3a + 2B = 2000, find the value of a + B
A=2
B=997
So a + B = 999
If a × B = 91 [AB is prime], then a + B = []
A×B=91
Then, a = 17 (3) B = 3 (17)
A+B=17+3=20
When a and B are prime numbers, then what is ab?
When a ≠ 1 and B ≠ 1, AB is a composite number
When a = 1 or B = 1, AB is prime
