[Commentary:
Powers of (b+c) up to (b+c)5. Each power is calculated from the previous one by multiplication.
Note the use of cossist r for a first power, z for a square, c for a cube, zz for a square-suare or fourth power, ßß for a sursolid or fifth power.
Below the main table is a list of the final sums, including the sixth power (zc), which has not been calculated on this page but which can be deduced from the pattern for the previous cases.
For a similar table see Add MS f. .
This table underpins the method of root extraction taught by Francois Viete in De numerosa potestatum resolutione (1600).
