Hi as usual no Z so have put this brain teaser on
Z FOR ZENZIZENZIZENZIC
Zenzizenzizenzic is an obsolete form of mathematical notation representing the eighth power of a number.
In arithmetic and algebra the eighth power of a number n is the result of multiplying eight instances of n together. So: n8 = n × n × n × n × n × n × n × n. Eighth powers are also formed by multiplying a number by its seventh power, or the fourth power of a number by itself.
Zenzizenzizenzic is an obsolete form of mathematical notation representing the eighth power of a number (that is, the zenzizenzizenzic of x is x8), 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 physician, mathematician and writer of popular mathematics textbooks, in his 1557 work The Whetstone of Witte (although his spelling was zenzizenzizenzike); he wrote that it "doeth represent the square of squares squaredly".
