The fibrous-root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root, with smaller roots branching off. The letters indicate where the root systems begin. A taproot is a large, central, and dominant root from which other roots sprout
The plant forms a fleshy tap root that is used as a storage and overwintering structure. [12] The central tap root can weigh up to 72 kg (159 lb). A four-year-old root grown under cultivation can reach a fresh weight of 45 kg (99 lb) and a length of 2.5 m (8.2 ft).
Such a number is algebraic and can be expressed as the sum of a rational number and the square root of a rational number. Constructible number: A number representing a length that can be constructed using a compass and straightedge. Constructible numbers form a subfield of the field of algebraic numbers, and include the quadratic surds.
The following list includes the continued fractions of some constants and is sorted by their representations. Continued fractions with more than 20 known terms have been truncated, with an ellipsis to show that they continue.

Transplanting juveniles is generally successful if the main root is left intact. Nīkau do not have a true tap root. Once the main root has been established to a fairly shallow depth of about 400 mm, roots take on form consistent with other palms. Successful transplanting is possible, but nīkau are very fickle if any trunk is present.
