WebLet us assume that √ 2 + √ 3 is a rational number. So it can be written in the form a b. √ 2 + √ 3 = a b. Here a and b are coprime numbers and b ≠ 0. √ 2 + √ 3 = a b. √ 2 = a b - √ 3. On squaring both the sides we get, ⇒ ( √ 2) 2 = a b - 3 2. We know that. WebAn irrational plus a rational gives an irrational.
