Question

prove that 2+
$\sqrt{3}$
is an irrational number

​

Answer 1

Answer:

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.
