Step-by-step explanation

Let us assume that  \sqrt{2} + \sqrt{3\\ are rational nos.

=>  \sqrt{2} + \sqrt{3\\= p/q

squaring on both sides

=> 2 + 3 + 2\sqrt{6} = p^{2}/q^{2}       { (a+b)^{2} identity }

=> root6 =  p^{2} - 6/2q^{2}

here LHS is irrational and RHS is rational.

therefore, LHS is not equal to RHS

=> our assumption is wrong

Therefore, \sqrt{2} + \sqrt{3\\ is an irrational no.
