Cube root Cube root In mathematics, a cube root of a number "x" is a number "y" such that "y" = "x". All real numbers (except zero) 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 , is 2, because 2 = 8, while the other cube roots of 8 are −1 + "i" and −1 − "i". The three cube roots of −27"i" are The cube root operation is not distributive with addition or subtraction. In
C-Cube Umesh Padval was brought in to run C-Cube Semiconductor in 1998. During the late 1990s, C-Cube was unable to repeat its runaway hits seen earlier in the decade. The company sold its DiviCom division to Harmonic Lightwaves in May, 2000 for nearly $1.7 billion. C-Cube Semiconductor (Nasdaq CUBED) was eventually sold to competitor LSI Logic in March 2001 in a stock transaction worth $878 million. LSI sold off the consumer products business (including what was C-Cube) to Magnum Semiconductor in 2007. C-Cube C-Cube Microsystems was an early company in video compression technology as well as the implementation of that technology
