the (number represented by the figure in the next) ghuna place (after it is taken into position) the cube (of this same quotient). 54. One (figure in the various groups of three figures) is cubie: two are non-cubic Divide (the non-cubic figure) by three times the square of the cube root. From the (next) non-cubic (figure) subtract the square of the quotient (obtamed as above and) multi- plied by three times the previously mentioned (cube-root of the highest cube that can be subtracted from the previous cubie figure) and (then subtract) the cube of the (above) quotient (from the next rubie figure as taken to position; With the help of the cube-rout-figures (so) obtained (and taken into position, the procedure is) as before. Examples in illustration thereof. 55. What is the cube root of the numbers beginning with 1 and ending with 9, all cubed; and of 4913; and of 18608672 56.
