Logarithmic Functions and Properties

The video tutorial covers the basics of logarithms, including properties and common logarithms. It explains how to solve logarithmic equations using calculators and provides a practical example. The tutorial emphasizes the use of base 10 logarithms due to their availability on calculators and demonstrates solving an equation by dividing both sides by a logarithm.

What is the property of logarithms that allows you to move the exponent in front of the log?

• Exponentiation Rule

• Logarithmic Shift

• Power Rule

• Base Change Rule

When taking the log of both sides of an equation, what can you do with the exponent?

• Add it to the log

• Multiply it by the log

• Drop it in front of the log

• Subtract it from the log

What is the base of the common logarithm?

• Base 2

• Base 10

• Base 7

• Base e

Why do we often use base 10 logarithms in calculations?
