(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find all x for which 2^{x}< 8 (where x is a natural number).

2. Relevant equations

Those pesky 12 properties.

3. The attempt at a solution

This could be done by simply testing values of x, but that approach is not very scalable. What is the correct way to start this (using only the basic properties of numbers)? What is Spivak looking for? Thanks.
