STUDENT VIDEO #3: Unit H Concept 7


  • What is this video about?
This video shows how to find the "treasure" from Unit H Concept 7, which is using the clues and find the right order of the values (letters) given. My group created the problem by using the numbers in the clues to multiply or divide the solution. In this video, we will review the properties of logs (product laws, quotient law, power law), factor branches, expanding logs, and log base b of b equals 1. We will use the given information and the properties of logs to write expanding logs. Then we will substitute the logs with the given letters and for log base b of b, we will just put 1. 

  • What does the viewer need to pay special attention to in order to understand the concept?
There are some important things that the viewer should notice. There is a property of log that helps this concept become more easier, log base b of b equals one. For example, log base 2 of 2 will be 1. So actually we have only extra clue. When we put the letters down, it needs to be in order to make the places of the logs correct. If the viewers put it incorrect, then they will not be able to find the "treasure" which means their answer is wrong.
