Question

Is √2/1 rational number

Answer 1

Answer:

As a fraction, 2 is 2/1

We can simplify the whole thing to 21, but still an odd exponent. Oh no, there is always an odd exponent. So it could not have been made by squaring a rational number! This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number.
