Answer:
Let 2+√3 is a rational number.
A rational number can be written in the form of p/q.
2+√3= p/q.
√3=p/q-2
√3= (p-2q)/q
p,q are integers then (p-2q)/q is a rational number.
But this contradicts the fact that√3 is an irrational number.
So, our supposition is false.
Therefore, 2+√3 is an irrational number.
Hence proved.
