Question

prove that the following are irrational.

1/v2​

Answer 1

Step-by-step explanation:

Let us assume 1/√2 is a rational number

Let us assume 1/√2 = r where r is a rational number

On further calculation we get

1/r = √2

Since r is a rational number, 1/r = √2 is also a rational number

But we know that √2 is an irrational number

So our supposition is wrong.

Hence, 1/√2 is an irrational number.
