Power signs

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.

Power of maths of powers

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, b² is usually read as b squared and b³ 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 e^x.

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