Question

plssss abswer the above question ​

Answer 1

That's easy. I'll tell you the approach, the rest you must do yourself. So, see that √2 and √3 both are irrational. So the sum has to irrational as well.

Alternatively, you can consider the both the terms as one whole and equate it to p/q for co primes p and q and q!=0 and prove by contradiction (which is available on internet) that it's not rational.

There you go!
