This character is a Other Number and is commonly used, that is, in no specific script. The codepoint represents the digit6.
The glyph is a superscript version of the glyph Digit Six. It has no designated width in East Asian texts. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. The word that U+2076 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In arithmetic and algebra the sixth power of a number n is the result of multiplying six instances of n together. So:
n6 = n × n × n × n × n × n.
Sixth powers can be formed by multiplying a number by its fifth power, multiplying the square of a number by its fourth power, by cubing a square, or by squaring a cube.
They include the significant decimal numbers 106 (a million), 1006 (a short-scale trillion and long-scale billion), 10006 (a quintillion and a long-scale trillion) and so on.
