Zenzizenzizenzic

Zenzizenzizenzic is an obsolete form of mathematical notation representing the eighth power of a number, dating from a time when powers were written out in words rather than as superscript numbers. This term was suggested by Robert Recorde, a 16th-century Welsh writer of popular mathematics textbooks, in his 1557 work The Whetstone of Witte; he wrote that it "doeth represent the square of squares squaredly". At the time Recorde proposed this notation, there was no easy way of denoting the powers of numbers other than squares and cubes. The root word for Recorde's notation is zenzic, which is a German spelling of the medieval Italian word censo, meaning "squared". Since the square of a square of a number is its fourth power, Recorde used the word zenzizenzic to express it. Some of the terms had prior use in Latin "zenzicubicus", "zensizensicus" and "zensizenzum". This is a condensed form of the Italian censo di censo, used by Leonardo of Pisa in his famous book Liber Abaci of 1202. Similarly, as the sixth power of a number is equal to the square of its cube, Recorde used the word zenzicubike to express it; a more modern spelling, zenzicube, is found in Samuel Jeake's Logisticelogia. Finally, the word zenzizenzizenzic denotes the square of the square of a number's square, which is its eighth power: in modern notation,
