Gleaming the Cube who gets kids to try an incredibly hard trick called the "Monster Cookie Pinwheel". When asked by the skaters what a Monster Cookie Pinwheel is, Skater McGee replies with, "A monster cookie pinwheel is when you skate up to a locomotives cow catch, you 360 punk buster to the second car, do a lemonade hand stand on the third car, a whipping-post ollie to the fourth car, a demon stomper on the fifth car, and a gleaming the cube off the sixth car, before dismounting the train." A reference to "gleaming the cube" was also made in season 3 of
Nth root real. Finally, if "x" is not real, then none of its "n"th roots is real. Roots are usually written using the radical symbol or "radix" with formula_2 denoting the principal square root of formula_3, formula_4 denoting the principal cube root, formula_5 denoting the principal fourth root, and so on. In the expression formula_6, "n" is called the "index", formula_7 is the "radical sign" or "radix", and formula_3 is called the "radicand". Since the radical symbol denotes a function, it is defined to return only one result for a given argument formula_3, which is called the principal "n"th root of formula_3.
