What is the latex code used in this forum of large bracket (and parenthesis) and subscript and superscript?

For example, the below parenthesis is too small:

$(x1 + \frac{1}{\frac{1}{x1}})$

Please refer to https://www.physicsforums.com/help/latexhelp/ for LaTeX used in this forum. Almost everything is given there.

For example, the below parenthesis is too small:

$(x1 + \frac{1}{\frac{1}{x1}})$

\left( x_1 +\dfrac{1}{\frac{1}{x_{1}}} \right)

$\left( x_1 +\dfrac{1}{\frac{1}{x_{1}}} \right)$

What is the latex code of large bracket?

\left( ... \right)

Note that \left and \right is used to get adjustable-size delimiters. You can also set the size manually, but I really recommend letting LaTeX take care of the formatting.

Information on all this can be found at https://en.wikibooks.org/wiki/LaTeX/Mathematics#Automatic_sizing

What is the latex code of large bracket?

Use "\left( ... \right)" for large parentheses, "\left[ ... \right]" for large square brackets, "\left\{ ... \right\}" for large curly brackets, "\left. F(x) \right|_a^b" if you want
$$\left. F(x) \right|_a^b $$

The left and right objects need not match, but every "\left" command must be followed by a "\right" command, possibly for a blank symbol, like this: "\left( ... \right." The commands "\left. " and "\right." insert blank symbols, as in (1) above. Note that those are "\left_dot = \left.", not "\left_blank_space = \left ".

The size of the brackets are automatically adjusted to match the contents of the brackets.
