On math.stackexchange I wanted the cube root of a fraction in display mode, and used $$\sqrt[3]{\frac ab}$$ to get it. The 3 comes out very small and low in the root sign. I also thought of $$^3\sqrt{\frac ab}$$ but the 3 comes out too far to the left.

May 26, 2011 · When I found that a simple x^(1.0/3.0) does not yield a graph in PGFplots for negative values of x, I attempted to define my own function for CubeRoot using pgfmathdeclarefunction as below. But, am...

Jan 9, 2012 · I've searched the Internet, but got nothing. In LaTeX, we can use \\square for square, but how can we get a cube, I want to use it in an equation. Here is the picture:

Is it possible to type a radical of a square root equation as \sqrt{} with any number inside the bracket ...

In fact, since your root symbol, p, has a longer lower-left spur and a smaller overall height than the \beta symbol that's used in the example code of the amsmath package's user guide does, you may want to use 3 rather than 2 as the argument of both \leftroot and \uproot in order to get a more balanced looking expression.

Jun 11, 2020 · Here's a solution that splits the full equation across three lines, with the help of a multline environment. The long square-root expression to the left of the = symbol is typeset using (...)^{1/2} notation in order to allow a line break.

Jun 22, 2014 · I wanted to use math variables (letters, not symbols) in the section heading, so, based on @Kilgore's hint to use \texorpdfstring, I defined a \hmath command for math-like letters (well, just roman italic letters) in the section heading:

Trying to take the nmth root of a results in nm overflowing off the radical sign. How can I extend the "tail" of the radical sign to contain all of nm? Answers to similar questions suggest using the amsmath package to adjust the placement of nm, but nm is too long to fit in the space provided.
