## Algebra and Trigonometry 10th Edition

$x=1$ or $x=e^2=7.389$
Use the Power Property: $\ln x^2=2\ln x$ $(\ln x)^2=2\ln x$ $(\ln x)^2-2\ln x=0$ $(\ln x)(\ln x-2)=0$ First Solution: $\ln x=0$ $e^{\ln x}=e^0~~$ (Use the Inverse Property: $e^{\ln x}=x$): $x=1$ Second Solution: $\ln x-2=0$ $\ln x=2$ $e^{\ln x}=e^2~~$ (Use the Inverse Property: $e^{\ln x}=x$): $x=e^2=7.389$
