To Prove that Root 5 is Irrational, we can use a contradiction method. Assume √5 is rational, meaning it can be written as a fraction of two integers, say p/q, where p and q have no common factors. So, √5 = p/q. Squaring both sides gives 5 = p²/q² or p² = 5q². This implies that p² is divisible by 5, meaning p must also be divisible by 5. Let p = 5k. Substituting this into the equation results in a contradiction, proving that our assumption was false. Hence, √5 is irrational and cannot be expressed as a simple fraction.
