Answer» We know √5 is irrational. Let 3 + √5 be rational So, 3 + √5 = r, where r be any rational √5 = r - 3 this is an absurd result because LHS is irrational and RHS is rational therefore a contradiction to our assumption that 3 + root 5 is irrational so 3 + √5 is irrational

Answer»

We know √5 is irrational.

Let 3 + √5 be rational

So, 3 + √5 = r, where r be any rational

√5 = r - 3

this is an absurd result because LHS is irrational and RHS is rational therefore a contradiction to our assumption that 3 + root 5 is irrational so 3 + √5 is irrational
