A rational is a number which could be written in the form of p/q or fraction. For Example \[\sqrt{4}\] = 2 which is understood 4/1. So \[\sqrt{4}\] is a rational number and \[\sqrt{3}\] is an irrational number.

That you get by writing those numbers as a multiplication of primes: 8=2*2*2, 12=2*2*3 and what is left in the squareroot is a prime, therefore irrational
