Answer
$x=e^{1.4}\approx4.0552$
Work Step by Step
We are given the equation $\ln(x)=1.4$. To solve for x, remember that the base of a natural logarithm is understood to be $e$.
Therefore, $\ln(x)=log_{e}x=1.4$.
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, $x=e^{1.4}\approx4.0552$.
