rootes as infinite. But their names thei take certainly, of the nombers that thei doe make.
A square roote.
So the roote of a square nomber, is called Square roote:
A cubike roote.
and the roote of Cubike nomber, is named a Cubike roote:
A squared
square roote.
In like sorte that roote is called a Squared square roote, whiche maketh a square of squares in nōber.
A sursolide roote.
And that roote is a Sursolide roote, that yeldeth a Sursolide nomber: in whiche sorte of multiplication, you maie procede infinitely, as I saied.
Notwithstandyng for your ease, I haue set foorthe here in a table, certain of the moste notable kindes of rooted nombers.
And to the intente you maie partly conceiue the reason of their names, I will after the table, set forth a brief explication of their names, with the protracture of the figures, that thei doe resemble in multiplications Geometricalle: where poinctes, lines, platte formes, or sound formes bee multiplied: and brynge foorthe other formes agreable to soche multiplications.
But first marke the table well: And it will giue you greate lighte, and aptnesse to vnderstande all that foloweth, moche the better.
For examples are the lighte of teachyng.The
