20 июл. 2010 г. · The irrationality of √2 is equivalent to that of 1+√2, which is equivalent to there being no length ℓ such that the hypotenuse and perimeter of ...

13 нояб. 2014 г. · The proof starts with assuming that √ 2 can be written as a ratio of two integers and then that this fraction can be reduced to its lowest terms.

23 мар. 2018 г. · But then, as long as both numbers are even, you can divide both sides by 2, and get two new numbers that have the same ratio.

20 июн. 2015 г. · Use strong induction to prove that √2 is irrational. [Hint: Let P(n) be the statement that √2≠n/b for any positive integer b.]

3 июн. 2015 г. · The square root of two is irrational. Proof. The boxed statement is true. (By the Lemma.) If the boxed statement is true, then the ...

25 нояб. 2010 г. · Yes. In fact, for every integer k and every n>1, the nth root of k is either an integer or irrational. One way to prove it is to use exactly ...

9 сент. 2015 г. · The square roots are irrational, because you impose the condition that it must be the product of two equal numbers.

12 окт. 2016 г. · I am having a problem understanding this proof. Suppose that √2 was rational. Then there would exist positive integers a,b such that √2=ab. ...

20 окт. 2020 г. · It is a proof by contradiction. The assumption is that √ 2 is not irrational, ie √ 2 is rational. This means √ 2 =p/q for some integers p,q.
