Answer 2

Answer:  MARK ME AS BRAINLIEST

Step-by-step explanation:

Let us assume that √3 + 2√5 is a rational number.

Then,            √3 + 2√5 = a/b

                ⇒ √3 = a/b - 2√5

               ⇒ √3 = (a - 2√5b)/b

   Here, LHS is irrational but RHS is rational

Therefore, √3 + 2√5 is a irrational number
