Answer 1

Answer:

good question I will answer it later

Answer 2

Let's assume 3 + $\sqrt{5}$ is rational.

3 + $\sqrt{5}$ = p/q, where p and q are the integers and q ≠0.

Since p , q and 3 are integers. So, (p-3q)/q is rational.

but this contradicts the fact that \sqrt{5} is irrational.

This contradiction has arisen due to the wrong assumption that 3 + $\sqrt{5}$ is rational.

Hence 3 + $\sqrt{5}$ is rational.
