Cube root approximation is somewhat of a black art. Some implementations manipulate the exponent bits of the floating-point number; i.e. they arrive at an initial approximation by dividing the exponent by 3. 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 roots and square roots (although simpler expressions only in terms of square roots exist for all three solutions, if at least one of them is a rational number). If two of the solutions are complex numbers, then all three
The Cube (game show) If the Cube is beaten, Extreme Mode is unlocked, featuring more extreme versions of five popular games: Revolution, Pathfinder, Perimeter, Rebound and Momentum. The Cube (game show) The Cube is a British game show that aired on ITV from 22 August 2009 to 8 August 2015 and was hosted by Phillip Schofield. The show offers contestants the chance to win a top prize of £250,000 by completing challenges from within a 4m × 4m × 4m Perspex cube. It is based on the idea that even straightforward tasks become extremely challenging when confined and put under pressure inside a small,
