All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted See more The cube roots of a number x are the numbers y which satisfy the equation $${\displaystyle y^{3}=x.\ }$$ See more Cube roots arise in the problem of finding an angle whose measure is one third that of a given angle (angle trisection) and in the problem of finding the edge of a cube whose volume is twice that of a cube with a given edge (doubling the cube). In 1837 Pierre Wantzel proved … See more Cubic equations, which are polynomial equations of the third degree (meaning the highest power of the unknown is 3) can always be solved for their three solutions in terms of cube … See more • Methods of computing square roots • List of polynomial topics • Nth root • Square root See more Real numbers For any real number x, there is one real number y such that y = x.
