Learn How to Multiply and Simplify the Square Root of Two Numbers

The video tutorial explains how to multiply radicals by multiplying the radicands and emphasizes the importance of simplifying radicals before and after multiplication. It provides a step-by-step example of multiplying sqrt(3) and sqrt(6) to get sqrt(18), and then simplifying it to 3sqrt(2) by recognizing 9 as a square number. The tutorial concludes with a reminder to always simplify where possible.
