 Question 333527: i have understood the proof " square root of 2 is irrational" by contradiction method" but i have a quesiton in my mind: In that proof, we supposed sqrt(2) was rational with p/q in its simplest form and when it was proved that our supposition is wrong, it was automatically proved that square root 2 is irrational.... i tried the same with square root of 4 and supposed that it WAS a rational with p/q in its simplest form.. this is what happened: p/q = sqrt(4) p² / q² = 4 --> equation 1 p² = 4q² Now: p² / q² = 4q² / q² (since p² = 4q²) or, p / q = 4q / q but here, p/q is not in tis simplest form, so our supposition is wrong and square root of 4 is irrationa;... lol ... whats wrong with my solution???????
