Answer

$x=\frac{log(5)}{3log(6)}\approx.2994$

Work Step by Step

According to the logarithm property of equality $log_{b}a=log_{b}c$ is equivalent to $a=c$ (where a, b, and c are real numbers such that $log_{b}a$ and $log_{b}c$ are real numbers and $b\ne1$). We can use this property to solve for x. $6^{3x}=5$ Take the common logarithm of both sides (which has base 10). $log(6^{3x})=log(5)$ Use the power property of logarithms. $3x log(6)=log(5)$ Divide both sides by $3log(6)$. $x=\frac{log(5)}{3log(6)}\approx.2994$
