Answer 2

Step-by-step explanation:

let us assume that 2+√3 is a rational number

so that a and b both co primes will exist

2+√3 = a/b

√3 = a/b - 2

√3 = a-2b/2

a-2b/3 is a rational number so that√3 should be a rational number

But it is not a rational number

this contradicates that 2+√3 is an irrational number
