Prove that sqrt(3) is irrational 相关知识点: 试题来源: 解析 √3是无理数。 假设√3是有理数,则存在互质的正整数a和b,使得√3 = a/b。平方得3 = a²/b² ⇒ a² = 3b²,因此3整除a²。根据欧几里得引理,3必然整除a,即a=3k(k为正整数)。代入得(3k)²=3b² ⇒ 9k²=3b...

Prove that 2 is irrational. 相关知识点: 试题来源: 解析 Assume that 2 is rational, so 2= where m and n have no common factor. Squring⇒2=(m^2)/(n^2)⇒2n^2=m^2 2n2 is a multiple of 2 =2n2 is even m2is even m is even. So let m = 2p. In equation this gives 2n^...

Prove that the square root of 3 is irrational. Does a similar argument work to show that the square root of 6 is irrational?Proofs:It is important that we prove statements to ensure we are correct and are using adequate logic. To prov...
Let 3 +2 is rational.Therefore, we can find two co-prime integers a, b (b ≠ 0) such that3+2 =→2=-3→=Since a and b are integerswill also be rational and therefore, is rational.This contradicts the fact that is irrational.Hence, our assumption that 3+2 isrational is false.The...
A)Prove that {eq}\sqrt{3},\sqrt{5} \space and \sqrt{6} {/eq} are irrational. Why doesn't this prove work for{eq}\sqrt{4} {/eq}? B) Prove that {eq}\sqrt[3]{2}\space and \sqrt[3]{3} {/eq} are irrational Rational and...
Proof by contradiction: assume that 2 is a rational and can be written where a and b are both non-zero integers and have no common factors. √2=a/b⇒√(2b)=a⇒2b^2=a^2 2 a2 must be a even, so a must also be even, which means it can be written as 2k, where k is an...
