Aligned starts of subscript and superscripts

Question

What's the code for this one?

I've tried this code:

{{a_1}^{{j_1} \left(g \right)}}{{a_2}^{{j_2} \left(g \right)}}{{a_3}^{{j_3} \left(g \right)}} \ldots

Answer 1

• Drop the double pairs of curly braces around a_1, a_2 and a_3

• Drop all \left and \right modifiers -- they do absolutely nothing here except create code clutter

\documentclass{article}
% \usepackage{newtxtext,newtxmath} % optional: Times Roman clone
\begin{document}
\[
a_1^{j_1(g)} a_2^{j_2(g)} a_3^{j_3(g)} \dots
\]
\end{document}
