What's the little number on the top of a number w/ unit?

I want to ask what is the little numbers on top/over any random number? For example, 75 in² and 125 ft with the little 3 on top like in the 75 in². What is it called and what does it mean is my question. I couldn't find anything online since I don't know what it is called.

Note that 'random number' has a special meaning in computing and mathematics. I would use 'arbitrary number' ;-)

In terms of formatting, numbers and letters that appear in the top half of a line are in superscript. Similarly, numbers in the bottom half of a line would be called subscript. "Super" and "sub" describe their position over or under the main text.
In your examples, these superscript numbers stand for a mathematical exponent or power as applied to a unit of measurement. If I were reading it out loud, I might say "seventy-five inches squared," or (more clearly) "seventy-five square inches." It means that I am talking about a unit of distance extending in two dimensions. It's a measurement of surface area, just like houses can be measured in square feet (ft2) and land can be measured in square miles (mi2). The cubic version (in3) would refer to a measurement across three dimensions, or a measurement of volume.
Other measurements can also be squared or cubed, especially when doing calculations in STEM fields, but square inches/feet/miles are the most common examples of this in the US.

This is a good point: superscript is a typographic term, whereas exponent and power describe the mathematical usage. It's anybody's guess which one OP had in mind.

Of course you could be really evil and mean "75 inches, see footnote two". Then it would be a superscript but not an exponent.

The general term for a number (or other text) written like this is superscript.
The term in2 refers to square inches, which is the amount of area in a square with sides an inch in length.
Likewise, if it were in3, it would be referring to cubic inches, which is the amount of volume in a cube with side lengths of an inch.
