WebbThis is an example of a proof using just the procedural rules. If at each step of the way, you obey the rules, you prove (arrive at the truth) that x = 8. The proof you are asking about in … Webb√8 = 8p/b which implies 8 = 64p²/b² which is: 1/8 = p²/b² or: b²/p² = 8 which implies b² = 8p² which implies 8 divides b² which means 8 divides b. 8 divides a, and 8 divides b, which is a contradiction because gcd (a, b) = 1 therefore, the square root of 8 is irrational. 1Thank You ANSWER Related Questions
