Expressions involving exponentials are combined by applying the following transformations:

$\mathrm{combine}\left({\ⅇ}^x{\ⅇ}^{-x}\,\exp \right)$

$1$

$\mathrm{combine}\left({\left({\ⅇ}^5\right)}^2{\ⅇ}^3\,\exp \right)$

${\ⅇ}^{13}$

$\mathrm{combine}\left({\ⅇ}^{x\+3\ln \left(y\right)}\,\exp \right)$

$y^3{\ⅇ}^x$

$\mathrm{combine}\left({\ⅇ}^{x\+\frac{3\ln \left(y\right)}{2}}\,\exp \right)$

${\ⅇ}^{x+\frac{3\ln \left(y\right)}{2}}$
