WebDec 14, 2024 · To prove sqrt (3) is irrational, we can use the proof by contradiction strategy famously used to prove the square root of 2 is irrational. We'll assume that the square root of 3 is NOT irrational ... Web3 is an irrational number Let 5+2 3 is a rational number ∴ we can write 5+2 3= qp, where p and q are integers ⇒2 3= qp−5= qp−5q 3= 2qp−5q Here, 2qp−5q is a rational number So, 3 is also a rational number. But it is given that 3 is irrational number. ⇒ our assumption was wrong ⇒5+2 3 is an irrational number. Solve any question of Real Numbers with:-
Proof: Square Root of 3 is Irrational - YouTube
WebProve that √3 is an irrational number. Solution : Let √3 be a rational number. Then it may be in the form a/b √3 = a/b Taking squares on both sides, we get 3 = a2/b2 3b2 = a2 a2 divides 3 (That is 3/a2) Then a also divides 3. Let a = 3c 3b2 = a2 By applying the value here, we get 3b2 = (3c)2 3b2 = 9c2 b2 = 3c2 b2 divides 3 (That is 3/b2) WebI have to prove that √3 is irrational too, as a homework. I have done it as follows, ad absurdum: Suppose √3 = p q with p / q irreducible, then 3q2 = p2 2q2 = p2 − q2 2q2 = (p + q)(p − q) Now I exploit the fact that p and q can't be both even, so it is the case that they are either both odd, or have different parity. ieee topics 2022
