To determine the subset of real numbers to which 10−−√ belongs, we need to consider whether it is a rational or irrational number.

A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. An irrational number cannot be expressed as a fraction and its decimal representation goes on indefinitely without repeating.

In this case, since the square root of 10 is not a perfect square, 10−−√ is an irrational number. Therefore, the subset of real numbers to which it belongs is "2. irrational numbers."
