Power refers to the result of power operation. N m means n times m (according to six textbooks, this formula means m times n). The result of taking m of n as power is called m power of n, where n is called base and m is called exponent (written as superscript). When superscript cannot be used, for example, in programming languages or e-mails, it is usually written as n m or n**m, or it can be written as n↑m with the symbol of low Dana arrow, which is read as "m power of n" or m power of n..
