Answer
$\log_{\frac{1}{3}}{4}$ or $\frac{\log4}{\log{\frac{1}{3}}}$ or $\frac{\ln4}{\ln{\frac{1}{3}}}$
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.
$\log_{\frac{1}{3}}{4}$ or $\frac{\log4}{\log{\frac{1}{3}}}$ or $\frac{\ln4}{\ln{\frac{1}{3}}}$
