Webb27 juli 2024 · Two rational numbers cannot sum to an irrational number so we have a contradiction. Therefore 2 + 3 is irrational. We can say 2 + 3 = I and come to the same result/conclusion for I + 5. In this case we reach the assumption that I 2 − 5 is rational. But I 2 − 5 = ( 2 + 3) 2 − 5 = 5 + 2 6 − 5 = 2 6 which is irrational and another contradiction. Webb23 feb. 2024 · Hence, 5 – 2√3 is an irrational number. ← Prev Question Next Question →. Find ... Show that 5 - 2√3 is an irrational number. asked Apr 22, 2024 in Number System … WebbSolution : Consider that √2 + √3 is rational. Assume √2 + √3 = a , where a is rational. So, √2 = a - √ 3 By squaring on both sides, 2 = a 2 + 3 - 2a√3 √3 = a 2 + 1/2a, is a contradiction as the RHS is a rational number while √3 is irrational Therefore, √2 + √3 is irrational.
