Significance of $e^\pi$

95 Views Asked by At

I know that $$\sqrt{e^\pi}=\sqrt[i]{i}$$ which is quite a nice result, and that it is transcendental. Does the constant $e^\pi$ have any other significance? Thanks. I realize this is quite a trivial question, but I'm just curious.

The expression $\sqrt[i]{i}$ is in most contexts meaningless. Even the square root of a complex number is generally ill-defined, let alone complex roots. To see the issue, consider that I could also write $e^{3 \pi} = e^{\frac{ 3 \pi i}{i}} = \sqrt[i]{e^{3 \pi i}} = \sqrt[i]{i}$.
