  2. Solution in radicals - Wikipedia

    en.wikipedia.org/wiki/Solution_in_radicals

    A solution in radicals or algebraic solution is an expression of a solution of a polynomial equation that is algebraic, that is, relies only on addition, subtraction, multiplication, division, raising to integer powers, and extraction of n th roots (square roots, cube roots, etc.). A well-known example is the quadratic formula

  3. Time bomb (software) - Wikipedia

    en.wikipedia.org/wiki/Time_bomb_(software)

    The first use of a time bomb in software may have been in 1979 with the Scribe markup language and word processing system, developed by Brian Reid.Reid sold Scribe to a software company called Unilogic (later renamed Scribe Systems [2]), and agreed to insert a set of time-dependent functions (called "time bombs") that would deactivate freely copied versions of the program after a 90-day ...

    en.wikipedia.org/wiki/Pomodoro_Technique

    Set the Pomodoro timer (typically for 25 minutes). [1] Work on the task. End work when the timer rings and take a short break (typically 5–10 minutes). [5] Go back to Step 2 and repeat until you complete four pomodori. After four pomodori are done, take a long break (typically 20 to 30 minutes) instead of a short break.

  5. Nested radical - Wikipedia

    en.wikipedia.org/wiki/Nested_radical

    In the case of two nested square roots, the following theorem completely solves the problem of denesting. [2]If a and c are rational numbers and c is not the square of a rational number, there are two rational numbers x and y such that + = if and only if is the square of a rational number d.

  6. Radical of an integer - Wikipedia

    en.wikipedia.org/wiki/Radical_of_an_integer

    In number theory, the radical of a positive integer n is defined as the product of the distinct prime numbers dividing n. Each prime factor of n occurs exactly once as a factor of this product: r a d ( n ) = ∏ p ∣ n p prime p {\displaystyle \displaystyle \mathrm {rad} (n)=\prod _{\scriptstyle p\mid n \atop p{\text{ prime}}}p}

  7. Bring radical - Wikipedia

    en.wikipedia.org/wiki/Bring_radical

    Plot of the Bring radical for real argument. In algebra, the Bring radical or ultraradical of a real number a is the unique real root of the polynomial + +.. The Bring radical of a complex number a is either any of the five roots of the above polynomial (it is thus multi-valued), or a specific root, which is usually chosen such that the Bring radical is real-valued for real a and is an ...

  8. Radical 8 - Wikipedia

    en.wikipedia.org/wiki/Radical_8

    Radical 8 or radical lid (亠部), whose meaning as an independent word is unknown, but is often interpreted to be a "lid" when used as a radical, is radical 23 of the 214 Kangxi radicals and consists of two strokes. In the Kangxi Dictionary, there are 38 characters (out of 49,030) to be found under this radical.

  9. Time bomb - Wikipedia

    en.wikipedia.org/wiki/Time_bomb

    A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...
