Note 40 — BOOK I[1] THE PHILOSOPHERS
Francis Legge translation
κυβισθῇ, involvit, Cr. It cannot here mean “cubed.” Another mistake occurs in the same sentence, where it is said that the square multiplied by the cube is a cube. The sentence is fortunately repeated with the needful correction in Book IV, p. 116 infra. Macmahon gives the proper notation as (a2)2 = a4, (a2)3 = a6, (a3)3 = a9.
