...number contains three times as many figures, or three times as many less one or two, as its cube root, and the number of periods will indicate the number of figures in the root. 3a2= 3.(30)2 Заб = 3.(30).5 62 = (5)2 3 a2 + 3 ab + fr3«2= 3(350)2 3a6 = 3.(350).0 6* = (O)2 3...

...This is done by pointing off the number into periods of two figures each, beginning at ike rig/it. The number of periods will indicate the number of figures in the root. Thus, the square root of 83,740,801 must contain 4 figures, since, pointing off the periods, we get...
