Answer
$e^{-3.7}$, $0.0247$
Work Step by Step
Based on the definition of the natural logarithm, we know that $ln(x)=log_{e}x$.
Furthermore, recall that $log_{b}x=y$ is equivalent to the statement $b^{y}=x$ (where $x\gt0$, $y$ is a real number, and $b\gt0$ and $b\ne1$).
Therefore, $ln(x)=log_{e}x=-3.7$ is equivalent to $e^{-3.7}=x$. We know that $x=e^{-3.7}\approx0.0247$.
