To the completed divisor add the figure last placed in the root, for a new divisor, with which proceed as before. Ex.--Required the square root of 331776. Ans. 576. 331776 ( 576 root. 25 576 Note 1. If there is a remainder after all the periods are used, the root may be continued decimally by annexing periods of two ciphers to each remainder. Note 2. Any figure of the root is an integer, or a decimal, according as the period from which it arises is an integer or decimal. Note 3. The root of a fraction is found by taking the roots of its terms, if it can be done exactly; if not, the fraction must be reduced to a decimal, and its root taken.

Find a mean proportional between 4 and 36; 42J and 4; 16 and 9; 52 and 12; 7 and 135; 2-16 and-75. Note 2. The side of a square equal in area to any given surface is the square root of the given area. 29. The area of a circle is-7854; required the side of a square equal in area thereto. 30. A gentleman has a fish-pond, in the form of a triangle, containing 480 perches; he wishes another of equal area, in the form of a square; required its side. 31.
