Rectangles of area 6, including 2x3 and 3x2 (solid black), and a square of side geometric mean of 2 and 3, or square root of 6 (red dashed); plus a square of side arithmetic mean of 2 and 3 (black dotted) with area 6.25 Distances between vertices of a double unit cube are square roots of the first six natural numbers.
Legend has it that it was taken from the Arabic letter "ج" , which is the first letter in the Arabic word "جذر" (jadhir, meaning "root"). [1] However, Leonhard Euler [ 2 ] believed it originated from the letter "r", the first letter of the Latin word " radix " (meaning "root"), referring to the same mathematical operation .
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. [1] Also useful is this generalized continued fraction, based on the nth root method: If x is a good first approximation to the cube root of a and =, then:
