Finding the Approximate Value of an Irrational Number

The video tutorial explains how to represent irrational numbers on a number line using a three-step process, demonstrated with the example of sqrt 7. The steps involve drawing a number line, constructing a vertical line, and using a compass to find an intersection point. The tutorial also introduces formulas for generalizing this method to any irrational number, emphasizing the geometric representation and approximation of square roots.
