WebShow that 3 + √2 is an irrational number Answer: Let’s assume on the contrary that 3 + √2 is a rational number. Then, there exist co prime positive integers a and b such that 3 + √2= a/b ⇒ √2 = a/b - 3 ⇒ √2 = (a - 3b)/b ⇒ √2 is rational [∵ a and b are integers ∴ (a - 3b)/b is a rational number] This contradicts the fact that √2 is irrational.

WebNov 28, 2024 · Solution: Let us assume, to the contrary that 5 + 3√2 is rational. So, we can find coprime integers a and b (b ≠ 0) such that 5 + 3√2 = a/b => 3√2 = a/b - 5 => √2 = (a - 5b)/3b Since a and b are integers, (a - 5b)/3b is rational. So, √2 is rational.

WebUse proof by contradiction to show that √ 2+ √ 3 ≤ 4. Solution: Suppose not. That is, suppose that √ 2+ √ 3 >4. Then (√ 2+ √ 3)2 >16. (All the numbers involved are positive.) So 2+2 √ 2 √ 3+3 16. So 2 √ 2 √ 3 >11. Squaring both sides again, we get 4 · 2 · 3 >121. That is 24 >121. But this last equation is obviously false ... WebLet us assume that √ 2 + √ 3 is a rational number.
