# How do you simplify ln (e* e * e)?

$\ln \left(e \cdot e \cdot e\right) = \ln \left({e}^{3}\right) = 3$
Natural logarithm $\ln \left(x\right) : \left(0 , \infty\right) \to \mathbb{R}$ and the natural exponential function ${e}^{x} : \mathbb{R} \to \left(0 , \infty\right)$ are inverses of one another.
So $\ln \left({e}^{x}\right) = x$ for $x \in \mathbb{R}$ and ${e}^{\ln \left(x\right)} = x$ for $x \in \left(0 , \infty\right)$
