In this video, the concept of Invariant Property is reviewed and the importance of paying attention to signs when deciding to use it is emphasized. In the first part of the video, the differences between even indices/exponents and odd indices/exponents are quickly repeated, and then more general reflections are made that will help to better understand what follows. In the second part of the video, how to proceed operationally to try to minimize sign errors when using the Invariant Property with Radicals is explained. At the end of the video, the viewer will have understood how to operate in order to avoid making sign errors when using the Invariant Property with Radicals. ______________________________________________________________ Download the Exercises: https://drive.google.com/drive/folder...
