The class number of a number field is by definition the order of the ideal class group of its ring of integers. Thus, a number field has class number 1 if and only if its ring of integers is a principal ideal domain (and thus a unique factorization domain). The fundamental theorem of arithmetic says that Q has class number 1.
Widespread sounding of the word occurs through the name of the company Google, with the name "Google" being an accidental misspelling of "googol" by the company's founders, [9] which was picked to signify that the search engine was intended to provide large quantities of information. [10]

Eventually, they changed the name to Google; the name of the search engine was a misspelling of the word googol, [23] [40] [41] a very large number written 10 100 (1 followed by 100 zeros), picked to signify that the search engine was intended to provide large quantities of information. [42]
Such a number is algebraic and can be expressed as the sum of a rational number and the square root of a rational number. Constructible number: A number representing a length that can be constructed using a compass and straightedge. Constructible numbers form a subfield of the field of algebraic numbers, and include the quadratic surds.
