Chapter 6.2
Evaluating logarithms without a calculator
What You'll Learn
Convert logarithmic expressions to exponential form to solve for unknown values
Apply the property that log base b of 1 always equals zero
Recognize that log base b of b always equals one
Evaluate logarithms by finding common bases and equating exponents
Use the inverse property: b to the power of log base b of A equals A
What You'll Practice
1
Converting logs to exponential form and solving for variables
2
Evaluating logs with fractional and negative exponents
3
Simplifying expressions using rational exponents and radicals
4
