I would like to have a bigger subscript S under the underbrace in the following equation and appreciate your help.
\begin{align}
K&=\frac{E}{(1+i)^r}\cdot \underbrace{\left (1+\frac{1}{(1+i)^{g}}+\frac{1}{(1+i)^{2\cdot g}}+\frac{1}{(1+i)^{3\cdot g}}+...+\frac{1}{(1+i)^{(n-1)\cdot g}}+\frac{1}{(1+i)^{n\cdot g}}\right )}_S\\
\end{align}

Just use
_{\textstyle S}
, perhaps adding\mathstrut
to give a bit more room.Here a couple of examples, the second uses
multlined
(which requiresmathtools
) for splitting the big underbraced object into two lines:Notes: never use
align
for a single line display; avoid...
and prefer\dots
.I'd also write
2g
,3g
and so on, without\cdot
, unless this is not ordinary multiples and\cdot
denotes a special action.
