The video provides two methods for rationalizing denominators: multiplying the top and bottom of the fraction by the root (for simple square roots) or by the conjugate (for square roots that involve a number +/- the root). The instructor demonstrates how to use these methods and provides step-by-step examples for each. The video also explains the historical reasons for rationalizing denominators and how it helps simplify calculations.\n
