Question

9) Prove that 3 +√ 5 is an irrational number.​

Answer 1

$\huge\red{Answer}$

Let us assume that 3+√5 is a rational number.

⇒3+5=pq

, where p and q are the integers and q ≠0.

⇒5=pq-3=p-3qq

Since p , q and 3 are integers. So,

p-3qq is a rational number.

⇒5 is also a rational number.

but this contradicts the fact that

5

is an irrational number.

This contradiction has arisen due to the wrong assumption that 3+5is a rational number.

Hence, 3+5 is an irrational number.
