If √2+√3=r∈Q, then r2−52=√6∈Q. ... Then its square is rational, because multiplying rationals gives a rational. But (√2+√3)2=2+2√6+3 is irrational because the sum of an irrational and a rational (5) is irrational, so we have a contradiction.

Then its square is rational, because multiplying rationals gives a rational. But (√2+√3)2=2+2√6+3 is irrational because the sum of an irrational and a rational (5) is irrational, so we have a contradiction. You'd have to prove that the sum of two irrational numbers yields an irrational number first.

The square root of 5, i.e., √5, is an IRRATIONAL (emphasis, mine) number, not a rational number, because √5 = 2.236 (rounded to 3 decimal places) does not fulfill the definition of a rational number.
