$x = e^{- 3}$ $x=e^(-3)$

Explanation:

Given
$XXX e^{4} x - e = 0$ $color(white)("XXX")e^4x-e=0$
then
$XXX e^{4} x = e$ $color(white)("XXX")e^4x=e$
and (after dividing both sides by $e^{4}$ $e^4$
$XXX x = e^{- 3}$ $color(white)("XXX")x=e^(-3)$

(Using a calculator for an approximation: $e^{- 3} = 0.049787068$ $e^(-3) = 0.049787068$ )

$x = \frac{1}{4}$ $x=1/4$

Explanation:

$e^{4 x} - e = 1 and adding e to both sides$ $e^(4x)-e=1 " and adding e to both sides"$

$e^{4 x} = e^{1} and since the bases (e) are equal, then$ $e^(4x)=e^1" and since the bases (e) are equal, then"$

$4 x = 1 \Rightarrow x = \frac{1}{4}$ $4x=1rArrx=1/4$
