Therefore, 2+5√3=a/b (where a and b are co prime) 5√3=a/b-2 5√3=a-2b/b √3=a-2b/5b Therefore, a-2b/5b is in the form of a/b which is rational number. But,this is contradicts the fact is that √3 is irrational number.
WebbSolution : Consider that √2 + √3 is rational. Assume √2 + √3 = a , where a is rational. √3 = a 2 + 1/2a, is a contradiction as the RHS is a rational number while √3 is irrational. …
Webb3 + 2√5 is irrational. Solution : Let 3 + 2√5 be a rational number. Then it may be in the form a/b 3 + 2√5 = a/b Taking squares on both sides, we get 3 - (a/b) = 2√5 (3b - a)/b = 2√5 (3b - a)/2b = √5 a, b, 3 and 2 are rational numbers. Then the simplified value of (3b - a)/2b must be rational. But it is clear that √5 is irrational. justin bibb american universityWebbFrom equations 2 and 3, we get that 3 is the common factor of p and q which contradicts that p and q are co prime.
