the most basic without any mathematical prove is that if any integer is added to any irrational no. then the sum will be an irrational no. only

Let us assume that √3 + 1 is a rational number

Then , it is of the form p/q where p and q are integers and q =/= 0

So , √3 + 1 = p/q

=> √3 = p/q -1

=> √3 = (p - q)/q

Here (p-q)q is rational

So , √3 is also rational

But this contradicts the fact that √3 is irrational

This contradiction arises due to our wrong assumption that √3 + 1 is rational

Hence √3 + 1 is irrational

Hope it helped you...
