Answer 1

Answer:

If given √2 is irrational, follow the given answer.If √2 is not given irrational then we to prove √2 is irrational.

Step-by-step explanation:

let 4+3√2 be rational, (where a and b are co prime),4+3√2=a/b,√2=(a-4b)/3b,here a,4,b,3 are integers so as √2 is also integer,this contradicts the fact that √2 is irrational,therefore 4+3√2 is irrational
