(Problem Posed by Manoj Eswar)
Find all prime nnumber \(p\), \(q\) and \(r\) such that
\(2p+3q = 6r\).
Justify your asnwer and send it to us at dep.math.svc@gmail.com
Note. A natural number \(p\) is said to be a prime number if its only divisors are \(1\) and \(p\).
(p,q,r) = (3, 2, 2) is the only solution
ReplyDeleteOkay. We shall look for other answers.
DeleteSuppose a•p+b•q=ab•r, where a,b,p,q and r are prime. Then when will be p=b ?
