Is √ 3 an irrational number?

Answer: Consequently, p / q is not a rational number. … This demonstrates that √3 is an irrational number.

Is 2 an irrational number?

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. In other words, the square root of 2 is irrational.
