Assume that the total of √3 +√ 5 is a rational number. Now, it can be written in the form a/b: a/b = √3 + √5 a and b are coprime numbers and b ≠ 0 Solving √3 + √5 = a/b On squaring both sides, we get, (√3 + √5) 2 = (a/b) 2 (√3) 2 + (√5) 2 + 2 (√5) (√3) = a 2 /b 2 3 + 5 + 2√15 = a 2 /b 2

Webb12 juli 2024 · Answer: To Prove : (3 + 2√5)² is irrational No. First we simplify using identity, (a+b)² = a² + 2ab + b² (3 + 2√5)² = 3² + (2√5)² + 2×3×2√5 = 9 + 4×5 + 12√5 = 29 + 12√5 we use the result that √5 is an irrational no. we know that product of rational and irrational no is and irrational no. ⇒ 12 × √5 = 12√5 is an irrational no.
WebbSolution To prove: 2 + 3 3 is irrational, let us assume that 2 + 3 3 is rational. 2 + 3 3 = a b; b ≠ 0 and a and b are integers. ⇒ 2 b + 3 3 b = a ⇒ 3 3 b = a - 2 b ⇒ 3 = a - 2 b 3 b Since a and b are integers so, a - 2 b will also be an integer. So, a - 2 b 3 b will be rational which means 3 is also rational. But we know 3 is irrational (given). Webb19 jan. 2024 · Thalassokrator edited. #2.
