    The principal cube root is the cube root with the largest real part In the case of negative real numbers, the largest real part is shared by the two nonreal cube roots, and the principal cube root is the one with positive imaginary part So, for negative real numbers, the real cube root is not the principal cube root

  • Cubic equation - Wikipedia
    All of the roots of the cubic equation can be found by the following means: algebraically: more precisely, they can be expressed by a cubic formula involving the four coefficients, the four basic arithmetic operations, square roots, and cube roots
  • Square root - Wikipedia
    Notation for the (principal) square root of x For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 52 (5 squared) In mathematics, a square root of a number x is a number y such that ; in other words, a number y whose square (the result of multiplying the number by itself, or ) is x [1] For example, 4 and −4 are square roots of 16 because Every nonnegative real number x has a unique

  • Square root algorithms - Wikipedia
    Square root algorithms compute the non-negative square root of a positive real number Since all square roots of natural numbers, other than of perfect squares, are irrational, [1] square roots can usually only be computed to some finite precision: these algorithms typically construct a series of increasingly accurate approximations
