## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

Yes. Instead of applying $\quad \log_{e}e^{k}=k$, we apply $\quad \log_{10}e^{k}=k\cdot\log_{10}e$. (sample answer)
Taking the common logaritm on both sides, we would obtain $\log e^{0.06t}=\log 1500\qquad$ ... apply the power rule, $0.06t\log e==\log 1500\qquad$ ... divide with $(0.06\log e)$ $t=\displaystyle \frac{\log 1500}{0.06\log e}$ So, yes, we could have applied $\log$ instead of $\ln$.
