Tutorial

Unit H Concept 9 Part 1

This video will introduce the concept of EXPONENTIATING as a method for solving logarithmic equations. It is always important to check your solutions at the end to make sure (1) they make a true statement and (2) you don't have to take the log of a negative number once your solution is plugged in.

Unit H Concept 9 Part 2

This video will show a second type of logarithmic equations solved using exponentiating. Because the resulting equation will be a quadratic, we will now have two potential answers. I will also show you how to use your graphing calculator to assist in checking for extraneous solutions.
