How can I write e^(3j) in LaTeX?

I have tried many syntax, like $e^(3j)$ or $e^*{3j}$

Any help will be very well received.

    What about $e^{3j}$ or $e^{(3j)}$ depending on what you want. – moewe Aug 16 '15 at 10:42

    (at least) 3 people think this is well researched, it's also some how become a "hot question" - this is a prime example of what's wrong with the hot questions, people who know absolutely nothing come along and are like "Yeah, that's a good question" (3 upvotes is rather small, I've seen some 'if you knew what the [se site name] was about you wouldn't upvote this' hit as high as 65 upvotes) – Alec Teal Aug 16 '15 at 15:08

Group the exponent in curly braces, and use the ^ sign to make it a superscript. If you really need parentheses, add them inside the braces too.

\documentclass[border=10pt]{standalone}
\begin{document}
$e^{3j}$ or $e^{(3j)}$%a variable e
\quad
$\mathrm{e}^{3j}$% e as a constant
\end{document}

    I feel one should use \exp and define it to one's likings, but that's debatable – Bort Aug 16 '15 at 10:51
  • @Bort But there are times when one wants to write $\exp(blah)$ and times when one wants to write $\mathrm{e}^{blah}$. The former is well-suited to complicated expressions; the latter to simple ones. – David Richerby Aug 16 '15 at 15:30
