Identify an Irrational Number on a Number Line

The video tutorial explains how to identify an irrational number, specifically sqrt 10, on a number line. It begins by introducing the problem and the number line with points A, B, C, and D. The instructor then demonstrates how to use square roots to assign numerical values to these points. By comparing these values, the instructor identifies that point B best represents sqrt 10 on the number line.
