How to Write Powers in Text Format on Websites?

[Gringo123]

I have a few questions that I would like to post on this site involving powers. First of all, can someone please tell me how to write the small figures that represent powers? I can do it on Microsofy packages, but not on this site.

2^x = 2[*SUP]x[*/SUP] without the * (the X² button)

or [*tex)2^x[*/tex] without the * (check the Σ button)

When in advanced options for a reply or when starting a thread if you want 'to the power of' where it has the X^2 where the 2 is above the x click that and insert your value which is being put to the power of in the middle of the code i.e. x² is just x[.SUP]2[/SUP] just for example i put a fullstop in the first SUP.

I prefer the tex option, myself. Makes it easier to write other complicated math stuff.

$$(\frac{x}{2})^2 = \frac{x^2}{4}$$

Tex is very flexible and powerful. For example parenthesis, brackets and curly braces can be scaled with

\bigr \bigl \Bigr \Bigl \biggr \biggl \Biggr and \Biggl

$$\bigl({{x}\over{2}}\bigr)^2 = \frac{x^2}{4}$$

$$\biggl({{x}\over{2}}\biggr)^2 = \frac{x^2}{4}$$

$$\Bigl({{x}\over{2}}\Bigr)^2 = \frac{x^2}{4}$$

$$\Biggl({{x}\over{2}}\Biggr)^2 = \frac{x^2}{4}$$

x[.SUP]2[/sup]

If you see what looks like some fancy LaTeX work, such as the things in elect_eng's post, if you double-click the expression, you can see the script that he used that renders that way.

[tex]x^2 should give me x to the power of 2. here goes!

and x^2

You're missing the tex tags! [t ex] x^2 [/t ex] (remove the spaces between the t and e)

 

[Borek]

You need both opening and closing tag:

[tеx]x^2[/tеx] -> $$x^2$$
