Steps to Prove that Root 7 is irrational by using two methods
WebbWe can prove that root 7 is irrational also by using the contradiction method. To prove: We want to prove that root 7 is irrational. Proof: We will start with the contradictory statement of what we have to prove.Let us assume that square root 7 is rational. Now since it is a rational number, it can be written in the form p/q, where p, q ∈ Z, and coprime numbers, … Webb10 apr. 2016 · Let us assume that 7 - 2 2 be a rational number. So, we can write it in the form of p q, where p, q are integers and q ≠ 0. Therefore, 7 - 2 2 = p q ⇒ 2 = 1 2 7 - p q ⇒ 2 = 7 q - p 2 q ⇒ 7 q - p and 2 q are integers. ⇒ 7 q - p 2 q is rational number. ⇒ 2 is a rational number. But we know that 2 is an irrational number.
