Use of powers

Powers or exponents are mathematical text symbols (we will talk later about their meaning) that people had been texting from the times when ASCII encoding was developed. And you can type them right from your keyboard. I'll show you how to do it by using different techniques depending on your Operating System and tastes.

Exponentiation is a mathematical operation, written as bⁿ, involving two numbers, the base b and the exponent (or index or power) n. When n is a positive integer, exponentiation corresponds to repeated multiplication; in other words, is product of a number b multiplied by itself n times.

The exponent is usually shown as a superscript to the right of the base. The exponentiation bⁿ can be read as: b raised to the n-th power, b raised to the power of n, or b raised by the exponent of n, most briefly as b to the n. Some exponents have their own pronunciation: for example, is usually read as b squared and as b cubed.

The power bⁿ can be defined also when n is a negative integer, for nonzero b. No natural extension to all real b and n exists, but when the base b is a positive real number, bⁿ can be defined for all real and even complex exponents n via the exponential function ex.

Also this index symbols are used in chemistry to denote chemical elements (ex. ²⁴⁰ᶠPu, ⁵⁸ᵐCo).

Alt Codes

Shortcut technique that works on Desktops and most Laptops running MS Windows. You press Alt and, while holding it, type a code on Num Pad while it's turned on. Please, read a guide if you're running a laptop. You can type many frequently used symbols with this method.

Configure your keyboard layout in Windows so that you can type all additional symbols you want as easy as any other text. Takes about 5-10 minutes to set things up, but you'll be typing like a boss. You can assign infinity symbols and any other text characters to your keyboard using this technique.

There actually are 3 different ways to type symbols on Linux with a keyboard. But only third and fourth level chooser keys and unicode hex codes can produce mathematical power text symbols.
