The video tutorial covers the multiplication and division of radicals. It begins by explaining how to multiply radicals by multiplying the coefficients and the radicands separately, followed by simplifying the result. The tutorial then moves on to dividing radicals, emphasizing the importance of rationalizing the denominator to avoid leaving an irrational number. Finally, it discusses simplifying radicals by dividing the radicands and further simplifying the result.
