Question

prove that √2 is an irrational number ??? ​

Answer 1

Answer:

Problem statement: Prove that Root 2 is Irrational Number

Given: The number 2

• There are two methods to prove that √2 is an irrational number, and those methods are:

• By contradiction method
• By long-division method

Step-by-step explanation:

• The square root of a number is the number that gets multiplied to itself to give the original number. The square root of 2 is represented as √2. The actual value of √2 is undetermined. The decimal expansion of √2 is infinite because it is non-terminating and non-repeating. Any number that has a non-terminating and non-repeating decimal expansion is always an irrational number. So, √2 is an irrational number.
