Question 409903
{{{ln(e^x) = 3}}}
We start be rewriting this in exponential form. In general {{{log(a, (p)) = q}}} is equivalent to {{{p = a^q}}}. Using this pattern on your expression we get:
{{{e^x = e^3}}}
The only way these powers of e can be equal is if the exponents themselves are equal, too. So:
x = 3
