How do you put cubed or squared after a number

[Caroline]

Trying to put numbers into a table and want to put a cubed number how do you
get the litte 3?

 

[Stefan Blom]

Type 3 and then apply superscript formatting to it, for example by pressing
Ctrl+Shift+Plus sign.

 

[Peter T. Daniels]

If you only need superscript 1, 2, or 3, you can find these numbers in
Insert Symbol, go to Latin-1 Supplement range (dropdown at the upper
right), and there they are. They should appear in almost any font
you're using. (A few fonts have a whole separate range called
"Superscripts and Subscripts" with the rest of the digits.)

The advantage over using the "Superscript" format is that they aren't
miniaturized versions of the numbers, which look gray because the
lines get so thin, but they're drawn to look right with the letters
and numbers next to them. If you use them a lot, you can assign
keyboard shortcuts via the button at the bottom of Insert Symbol.

 

[Idaho Word Man]

You type a regular 3, and then select the 3 and format the font as
"superscript."
