Need help making a formula look larger and nicer in latex

Question

I'm trying to make this look nicer and more readable (brackets tall enough, fraction large enough to easily read, etc).

$((\frac{(x(1-\delta_{1}))}{(z(1-\delta_{3}))}(1-\delta_{4}))(y(1-\delta_{2})))(1-\delta_{5})$

Answer 1

Such a big formula should be displayed with the equation* environment (or equation if you want it to be numbered).

Several of the brackets you use are not necessary; if you want to emphasize the factor y(1-\delta_2), surround it with slightly larger parentheses.

\documentclass{article}
\usepackage{amsmath}

\usepackage{lipsum}% just for the example

\begin{document}

\lipsum*[3]
\begin{equation*}
\frac{x(1-\delta_{1})}{z(1-\delta_{3})}(1-\delta_{4})\bigl(y(1-\delta_{2})\bigr)(1-\delta_{5})
\end{equation*}
\lipsum[4]

\end{document}

Answer 2

Hope you need the nesting of brackets, which is possible with the usage of \left and \right command. LaTeX will check the nesting and match the bracket sizes by auto, please refer the below tag:

$\left(\left(\frac{(x(1-\delta_{1}))}{(z(1-\delta_{3}))}(1-\delta_{4})\right)(y(1-\delta_{2}))\right)(1-\delta_{5})$

and the output is look like that:

Hope this is what you expected, if not so, correct me with your exact requirement...
