  2. Cube (algebra) - Wikipedia

    en.wikipedia.org/wiki/Cube_(algebra)

    The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 2 3 = 8 or (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 xx 3 (often denoted y = x 3) that maps a number to its cube. It is an odd function, as (−n) 3 ...

  3. Cubic reciprocity - Wikipedia

    en.wikipedia.org/wiki/Cubic_reciprocity

    Cubic reciprocity is a collection of theorems in elementary and algebraic number theory that state conditions under which the congruence x 3 ≡ p (mod q) is solvable; the word "reciprocity" comes from the form of the main theorem, which states that if p and q are primary numbers in the ring of Eisenstein integers, both coprime to 3, the congruence x 3 ≡ p (mod q) is solvable if and only if ...

    A cube root of a number x is a number r ... Thus the next p will be the old p times 10 plus x. Subtract ... For the case in which x is negative and n is odd, ...

  5. Cube root - Wikipedia

    en.wikipedia.org/wiki/Cube_root

    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 ...

  6. Fourth power - Wikipedia

    en.wikipedia.org/wiki/Fourth_power

    In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n 4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube.

  7. Proof of Fermat's Last Theorem for specific exponents

    Since x and y are both odd, they cannot be equal. If x = y, then 2x 3 = −z 3, which implies that x is even, a contradiction. Since x and y are both odd, their sum and difference are both even numbers 2u = x + y 2v = x − y. where the non-zero integers u and v are coprime and have different parity (one is even, the other odd).

  9. Squared triangular number - Wikipedia

    en.wikipedia.org/wiki/Squared_triangular_number

    A square whose side length is a triangular number can be partitioned into squares and half-squares whose areas add to cubes. From Gulley (2010).The n th coloured region shows n squares of dimension n by n (the rectangle is 1 evenly divided square), hence the area of the n th region is n times n × n.
