size and location of cube root symbol [duplicate] Closed 12 years ago. 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.
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. \documentclass{article ...
Nov 7, 2017 at 1:36. You can write a mathematical expresion inline, within the text using a pair of single dollar signs, such as $ y = f(x) $, but when you want to display a mathematical expression outside the text, is very comfortable to use the double pair of dollar signs, but it isn't a good choice in LaTeX because, as Bernard says, it lead ...
37. The manfnt package offers \mancube and \manimpossiblecube: Those commands won't directly work in math mode, but you can use a \mbox; something like this: \mbox{\mancube}_{n} +(n+1)^{3} Of course, you could define a command if you are going to use the cube several times: @TorbjørnT. you're right.
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...
Update. Now \cuberoot and \fourthroot will load the large symbols automatically in unicode-math v0.8m (2018/07/29). It's actually U+221B and U+221C.
Yes, just make sure you are in math mode: example $\sqrt{}$, or if you want the horizontal line $\sqrt{\hphantom{99}}$, where the widthof{99} determines how wide it is. If you actually have a number just use $\sqrt{<num>}$. It's not clear what you're asking. Do you want a square root sign with nothing under it, or an nth root sign (like cube ...

I would expect the first three expressions to appear in regular size, and the last three to appear in script size. However, only the cube root is re-sized: I guess this means that \scriptsize doesn't do what I think it does … but, while I could buy that conclusion if \scriptsize didn't do anything, why does it re-size just one of the expressions?
