Chapter 4 - Section 4.5 - Exponential and Logarithmic Equations - 4.5 Exercises - Page 446: 4

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 $\frac{\ln4}{\ln{\frac{1}{3}}}$
