Question 544634
I understand that you have a question about {{{e^6}}}.
I do not know what your question is, but I can tell you that there is no less mysterious exact expression for that.
A number like {{{sqrt(2)}}} is irrational, but you can evaluate some algebraic expressions using that number and get to a satisfying, familiar answer. For example,
{{{(sqrt(2))^2=2}}}
No such luck with transcendental numbers, like {{{pi}}} or {{{e}}}.
