Showing Symbols: Square Root, Super/Sub Scripts, LaTeX

[chikis]

How do I indicate or show square root sign, super script and sub script? How do I use latex in the forum?

All of this is answered in our FAQ and HowTo.

The short version:
[noparse]√a₁²[/noparse]
Inline ##[/color]\sqrt{a_1^2}#[/color]#
$$[/color]\sqrt{a_1^2}$[/color]$

gives

√a₁²
Inline $\sqrt{a_1^2}$
$$\sqrt{a_1^2}$$
