In mathematics, a cube root of a number x is a number y that has the given number as its third power; that is =. The number of cube roots of a number depends on the number system that is considered. Every nonzero real number x has exactly one real cube root that is denoted x 3 {\textstyle {\sqrt[{3}]{x}}} and called the real cube root of x or ...
The cube of a number n is denoted n 3, using a superscript 3, [a] for example 2 3 = 8. The cube operation can also be defined for any other mathematical expression, for example (x + 1) 3. The cube is also the number multiplied by its square: n 3 = n × n 2 = n × n × n. The cube function is the function x ↦ x 3 (often denoted y = x 3) that
1 ⁄ 3, a fraction of one third, or 0. 3 in decimal. pre-decimal British sterling currency of 1 shilling and 3 pence; 1st Battalion, 3rd Marines, United States infantry battalion; One/Three, a 20; Loona 1/3, a Loona spin-off
If n is even, a complex number's nth roots, of which there are an even number, come in additive inverse pairs, so that if a number r 1 is one of the nth roots then r 2 = –r 1 is another. This is because raising the latter's coefficient –1 to the nth power for even n yields 1: that is, (–r 1) n = (–1) n × r 1 n = r 1 n.
In baseball, the statistic innings pitched (IP) is the number of innings a pitcher has completed, measured by the number of batters and baserunners that have been put out while the pitcher is on the pitching mound in a game. Three outs made is equal to one inning pitched. One out counts as one-third of an inning, and two outs as two-thirds of ...
Intuitively, guessing any number higher than 2 / 3 of what you expect others to guess on average cannot be part of a Nash equilibrium. The highest possible average that would occur if everyone guessed 100 is 66 + 2 / 3 . Therefore, choosing a number that lies above 66 + 2 / 3 is strictly dominated for every player. These ...
The biggest regret, shared by about one-third of retirees, was that they didn't save enough for retirement. You hear about nest eggs of $1 million or even $500,000 and it sounds like a lot of ...
A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is not considered as repeating.
