WebMar 22, 2024 · Let us assume 5√2 to be Rational. Then, 5√2 = a / b [ Where, a & b are co-prime and b ≠ 0 ] √2 = a / 5b. a / 5b is rational. But, we know √2 is Irrational. This … WebApr 6, 2024 · An irrational number is a number which non terminating as well as non recurring and cannot be expressed in the form of. a b. Complete step-by-step answer: Let us assume that. 5 + 2. is rational. Then, there exist coprime positive integers a and b such that. 5 + 2 = a b, b ≠ 0 ⇒ a = ( 5 + 2) b. Solving it further we get:-.
WebDec 14, 2024 · Proof: We can prove that root 5 is irrational by long division method using the following steps: Step 1: We write 5 as 5.00 00 00. We pair digits in even numbers. Step 2: Find a number whose square is less than or equal to the number 5. It is 2 which is a square of 4. Step 5: We use 2 as our divisor and 2 as our quotient. WebMay 3, 2024 · So, assume that 2+3root 5 is rational. 2+3root5=p/q,where p and q are coprimes and q not equals to 0. 3root 5=p/q-2. root 5=p/q-2/3. A rational number never equals to an irrational number. We assume that p and q are coprimes and q not equals to 0. so, our assumption is wrong. 2+3root 5 is an irrational number.
