Superscript

Superscript syntax: a^x

Subscript syntax: a_x

Note: Increase parentheses for complex subscripts

Fractions and Radicals

Fractional syntax: \frac{numerator}{denominator}

Root Syntax: \sqrt[how many times to square]{what's in root}

Notes:

Numerators or denominators that are too simple may not have parentheses.

Root formulas can be omitted if they are too simple.

Quadratic formulas can be omitted

There is a difference in the output of fractions in interlinear and intralinear formulas. If you want to force the fractions in inline mode to be displayed at the size of the interline mode, you can use \\dfrac, and vice versa with \\tfrac.

To write fractions in inline mode, you may like the effect of the \sfrac command provided by the xfrac macro package.

To typeset complex fractions, you should use the \cfrac command.
