Question

Prove that (2+√3)/5 is an irrational number.

Answer 1

Answer:

I can prove

Step-by-step explanation:

Let us assume that (2+√3)/5 is not an irrational number

Let the rational number be a

(2+√3)/5=a

2+√3=5a

√3=5a-2

Since 5a-2 is a rational

√3 is irrational

Rational≠Irrational

This is contradiction for our assumption

So (2+√3)/5 is an irrational number
