7.) Video: Simplifying Radicals
Video 1: Watch this video to see how I simplified the radicals in Practice 1. If you did not get the same answers as me, make sure you correct your errors. A second video is below... Video 2: There is a second video you can watch that shows extra examples. This video is for those of you who are still struggling with this concept. Please take notes on all the examples. This is a Khan Academy video and might be just what you need to grasp this concept. |

11.) Notes: Pythagorean Practice
Now that you know how to simplify radicals, you can easily find the missing side lengths of these right triangles without needing to round. Use what you have learned so far in this lesson to find the EXACT length of each missing side. Please also attempt the challenge problem. |
12.) Video: Pythagorean Practice
There are two different videos here. The first one show how I solved the first 3 practice Pythagorean Problems. The second video shows how I worked through the challenge problem. |
