Answer
$\ln{40,960}$
Work Step by Step
Recall:
(1) $n\cdot \ln{a}=\ln{a^n}$
(2) $\ln{a}+\ln{b}=\ln{(ab)}$
(3) $\ln{a}-\ln{b} = \ln{\left(\frac{a}{b}\right)}$
Use rule (1) above to obtain:
\begin{align*}
&=\ln{\left(8^4\right)}+\ln{10}\\
&=\ln{4096}+\ln{10}
\end{align*}
Use rule (2) above to obtain:
\begin{align*}
&=\ln{(4096\cdot 10)}\\
&=\ln{40,960}
\end{align*}
