An Egyptian fraction is the sum of a finite number of reciprocals of positive integers. According to the proof of the Erdős–Graham problem, if the set of integers greater than one is partitioned into finitely many subsets, then one of the subsets can be used to form an Egyptian fraction representation of 1.

If x is rational, it will have two continued fraction representations that are finite, x 1 and x 2, and similarly a rational y will have two representations, y 1 and y 2. The coefficients beyond the last in any of these representations should be interpreted as +∞; and the best rational will be one of z(x 1, y 1), z(x 1, y 2), z(x 2, y 1), or ...
The only positive integers that can be non-Brazilian are 1, 6, the primes, and the squares of the primes, for every other number is the product of two factors x and y with 1 < x < y − 1, and can be written as xx in base y − 1. [14] If a square of a prime p 2 is Brazilian, then prime p must satisfy the Diophantine equation
If D is a non-square natural number, then there is a natural number n such that: n 2 < D < (n + 1) 2, so in particular 0 < √ D − n < 1. If the square root of D is rational, then it can be written as the irreducible fraction p/q, so that q is the smallest possible denominator, and hence the smallest number for which q √ D is also an ...
whose solution is known as Beer–Lambert law and has the form = /, where x is the distance traveled by the beam through the target, and I 0 is the beam intensity before it entered the target; ℓ is called the mean free path because it equals the mean distance traveled by a beam particle before being stopped.
This is strictly correct given that a nonnegative real number a has a unique nonnegative square root and this is called the principal square root which is denoted by √ a. The symbol √ is called the radical sign or radix. For example, the principal square root of 9 is 3, which is denoted by √ 9 = 3, because 3 2 = 3 • 3 = 9 and 3 is
