Is a surd categorised as a real number?

Question

In the study of numbers would a surd be classed as real number?

Answer 1

Yes, it is a real number, but it is irrational (it can't be written in fraction form where both the numerator and denominator are integers)

On the other hand, imaginary numbers which are NOT real numbers, are the square roots of negative numbers.

Answer 2

Wow good question. I had to go research no luck.
