what's the problem with x=(-3)^(2/3) ???

according toWolframAlpha:

x ≈ -1.04 + 1.8i (a complex number)

according to MS Mathematics:

x ≈ 2.08

which is aslo what I came up with myself...

(-3)^(2/3)=

cbrt((-3)^2)=

cbrt(9)=

cbrt(3^2)=

3^(2/3)≈

2.08

I must say I'm a bit confused here...

When answering questions in the math- or physics-section I often need to write mathematical formulas, which is nearly impossible using this simple text-editor...

A very simple but very effective solution to this problem would be for Yahoo to implement LaTeX.

LaTeX is an easy to use, but very powerfull markup-language to generate a little image containing the desired formula and it can very easily be implemented in a website.

Does anyone know if this has already been proposed? And if so, is there a reason for Yahoo not to implement it?

I have seen answers that include links, so I know it is possible... I just don't know how.

When I copy/paste the URL, it just showes like plain text.

I already tried some BB-code-like things but it doesn't work either...
