v1.c8.s9.15

"(Divide the digits beginning with the units place into periods of) one *ghana* place and two *aghana* places. From the (last) *ghana* digit subtract the (greatest possible) cube; then taking down the remainder and the third *pada* (*i.e.*, the second *aghana* digit) divide it by thrice the square of the cube-root which has been permanently placed in a separate place; place the quotient in the line; subtract the square of this (quotient) multiplied by thrice the last root from the next (*aghana*) digit. Then as before subtract the cube (of the quotient) from its own place (*i.e.*, the *ghana* digit). Then take down again the third *pada* (*i.e.*, second *aghana* digit), and the rest of the process is as before. (This will give) the root."²
