Answer
$\log_{\frac{1}{2}}{12}$ or $\frac{\log12}{\log{\frac{1}{2}}}$ or $\frac{\ln12}{\ln{\frac{1}{2}}}$
Work Step by Step
Solve the exponential equation as a logarithm in the three forms shown in the example.
The forms are the log base x of y and the mathematical ways to find the log base x of y using the fraction with the common or natural log y over the common or natural log x.
$\log_{\frac{1}{2}}{12}$ or $\frac{\log12}{\log{\frac{1}{2}}}$ or $\frac{\ln12}{\ln{\frac{1}{2}}}$
