Using Logs to Expand an Expression
On the board log(xy) should not have base a since it was not written for the rest of the equation.
Also, ln x³(x² + 3 )^(1/4) should be written as ln [x³(x² + 3)]^(1/4). Only then x³ will also be raised to the power of 1/4.
How to use properties of logs to expand an expression with roots
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.

Staff Review
A challenging example to attempt as it incoperates more than one law.
