Empty Product - 0 Raised To The 0th Power

0 Raised To The 0th Power

Further information: Exponentiation#Zero to the zero power

In set theory and combinatorics, the cardinal number nm is the size of the set of functions from a set of size m into a set of size n. If m is positive and n is zero, then there are no such functions, because there are no elements in the latter set to map those of the former set into. Thus 0m = 0 when m is positive. However, if both sets are empty (have size 0), then there is exactly one such function — the empty function. For this reason, authors in combinatorics and set theory frequently define 00 to be 1 when it represents an empty product.

Famous quotes containing the words raised and/or power:

    The New Testament is remarkable for its pure morality; the best of the Hindoo Scripture, for its pure intellectuality. The reader is nowhere raised into and sustained in a higher, purer, or rarer region of thought than in the Bhagvat-Geeta.... It is unquestionably one of the noblest and most sacred scriptures which have come down to us.
    Henry David Thoreau (1817–1862)

    In Europe, charters of liberty have been granted by Power. In America ... charters of power [are] granted by liberty.
    James Madison (1751–1836)
