Exponents & Logs: Working With Logarithms 410

This lesson is part of the series: Exponents & Logarithms

This 67 minute exponents & logarithms lesson begins with the relationship between exponents and logarithms and focuses on solving for an unknown in a logarithmic equation and learning to evaluate logarithms with different bases:

This lesson will show you how to:
- change from exponential form to logarithmic form
- change from logarithmic form to exponential form
- identify and use a common log
- identify and use a natural log (ln, base e)
- solve for unknowns in a logarithmic equation
- evaluate logarithms, for example log base 7(49 cube root 7) + log base 27(3^3 times 81 ^1/2)
- find the number positi0n and the base position

This lesson contains explanations of the concepts and 32 example questions with step by step solutions plus 5 interactive review questions with solutions.
