How can I change the font for power such a way that the power symbol is rendered much smaller than the number 3 in the following formula? I need to sum (necessarily with \displaystyle) was much smaller number of 3.
\pdfoutput=0
\documentclass[fleqn]{article}
\usepackage[T2A]{fontenc}
\usepackage[cp1251]{inputenc}
\usepackage{concmath}
\usepackage{amsmath}
\begin{document}
\thispagestyle{empty}
\begin{displaymath}
3^{\displaystyle \sum_{n=0}^{\infty}\frac{(-1)^n}{2^n}}
\end{displaymath}
\end{document}
which renders as
But it does sum in power too large. How to make, that sum was, for example, is 10 times less than the number 3? Or 5 times less than the number 3? The number 3 to make very large. And sum to make very small. Possibly?
Best Answer
I show your original, followed by two alternatives. The first scales the summation to 20% of the original size. The second scales the 3 to 500% of the original size. The
\scaleobj
command is part of the scalerel package. It is similar to the\scalebox
command of the graphicx package, except that it defaults to math mode, and takes the current math style into account.
