In mathematics and statistics, sums of powers occur in a number of contexts: . Sums of squares arise in many contexts. For example, in geometry, the Pythagorean theorem involves the sum of two squares; in number theory, there are Legendre's three-square theorem and Jacobi's four-square theorem; and in statistics, the analysis of variance involves summing the squares of quantities.
The sum of the first nine primes up to 23 is a square: + + + = = and the sum of the first 23 primes is 874, which is divisible by 23, a property shared by few other numbers. [ 7 ] [ 8 ] It is the fifth factorial prime , [ 9 ] and since 14! + 1 is a multiple of 23, but 23 is not one more than a multiple of 14 , 23 is the first Pillai prime .
For example, 6 + 7 = 13 can be derived from 5 + 7 = 12 by adding one more. [ 36 ] Making ten : An advanced strategy uses 10 as an intermediate for sums involving 8 or 9; for example, 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14 .

Since a = n(n + 1)/2, these formulae show that for an odd power (greater than 1), the sum is a polynomial in n having factors n 2 and (n + 1) 2, while for an even power the polynomial has factors n, n + 1/2 and n + 1.
In arithmetic and algebra, the seventh power of a number n is the result of multiplying seven instances of n together. So: n 7 = n × n × n × n × n × n × n.. Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.
Using the same argument as before it becomes clear that the number on the gate is 13, and the ages 9, 2 and 2. [ 5 ] A criticism of this problem is that a household may have two children of the same age in terms of natural numbers, but different birthdays, such as children in a mixed-parent household.
