The word "zenzizenzizenzic" is an anachronistic mathematical term that represents the eighth power of a number. In other words, it means: \(X^8\). It is the square of a number's square squared. This word contains the most z's according to the Oxford English dictionary.
Another obsolete mathematical term, "zenzicube," was used to represent the sixth power of a number. In other words, it means: \(X^6\). It is the square of a number's cube.
Likewise, "surfolide" refers to the fifth power, while "second surfolide" refers to the seventh power. The term "biquadrate" refers to the fourth power.
Apparently, most of these words were developed when mathematicians employed words instead of numerical superscript to represent exponents.
