Prove that 2 is an irrational number. 相关知识点: 试题来源: 解析 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 ...
Question 1:Prove that v5 is irrational. 相关知识点: 试题来源: 解析 Let √5 is a rational number.Therefore, we can find two integers a, b(b ≠ 0) such that √5 =a/bLet a and b haveacommon factor other than 1.Then we can divide them by the common factor, andassume that a and...
