Use the change-of-base formul to rewrite the logarithm using the common logarithm or the natural logarithm.
`\log_9(24)`
First, write the exact answer. Do not round.
`\log_9(24)=`
Now, use a calculator to evaluate the logarithm. Round to four decimal places.
`\log_9(24)~~`
To use the change-of-base formula for converting `\log_9(24)` into a form that uses the common logarithm (base 10) or the natural logarithm (base e), remember that this formula is defined as: `\log_a x=\frac{\log_b x}{\log_b a}`where `a` can be any other base, typically `10` for common logarithms or `e` for natural logarithms. Choose one base to work with, and apply it consistently to both the numerator and the denominator.
