Answer
$x=e^{2.1}\approx8.1662$
Work Step by Step
We are given the equation $\ln(x)=2.1$. To solve for x, remember that the base of a natural logarithm is understood to be $e$.
Therefore, $\ln(x)=log_{e}x=2.1$.
If $b\gt0$ and $b\ne1$, then $y=log_{b}x$ means $x=b^{y}$ for every $x\gt0$ and every real number $y$.
Therefore, $x=e^{2.1}\approx8.1662$.
