what is the true solution to the equation below?\n$ln e^{ln x}+ln e^{ln x^{2}} = 2ln 8$\n$x = 2$\n$x = 4$\n$x = 8$\n$x = 64$
Answer
Explanation:
Step1: Use the property $\ln e^a=a$
$\ln e^{\ln x}+\ln e^{\ln x^{2}}=\ln x+\ln x^{2}$
Step2: Use the property $\ln a^{b}=b\ln a$ for $\ln x^{2}$
$\ln x+\ln x^{2}=\ln x + 2\ln x=3\ln x$
Step3: Rewrite the right - hand side using the property $b\ln a=\ln a^{b}$
$2\ln 8=\ln 8^{2}=\ln 64$
Step4: Solve the equation
Since $3\ln x=\ln 64$, and $3\ln x=\ln x^{3}$, then $\ln x^{3}=\ln 64$. So $x^{3}=64$, and $x = 4$.
Answer:
$x = 4$
