This shows 3√3 is irrational. The other way to prove this is by using a postulate which says that if we multiply any rational number with an irrational number, the product is always an irrational number. ogylvie thompson street bloemfontein https://trlcarsales.com

It's exactly the same as proving 2 is irrational. Suppose 5 = ( a b) 3 where a, b are integers and g c d ( a, b) = 1) [i.e. the fraction is in lowest terms]. The 5 b 3 = a 3 so 5 … WebbSolution. Verified by Toppr. Let us assume to the contrary that (√3+√5)² is a rational number,then there exists a and b co-prime integers such that, (√3+√5)²=a/b. 3+5+2√15=a/b. 8+2√15=a/b. 2√15= (a/b)-8. 2√15= (a-8b)/b. ogym moulin rochard mon compte
