I need to take the 1.16 root of x, do I show it as;

a) $\sqrt[1.16]{x}$

OR

b) $x^{\frac{1}{1.16}}$

Thanks

they're both exactly the same, but I would say b) is easier to work with and gets your point across more clearly.

I like (a), but that's only because I almost never see it, and I didn't know how to do it in latex until just now.

To use a calculator for a certain value of x, 1. leads to 2., so use 2. without worrying about root symbols.

yeah, I vote for b), too. More general and lends itself for easy inclusion into equations, polynomials, etc.
