- Fourth_power abstract "In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So:n4 = n × n × n × nFourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares.The sequence of fourth powers of integers (also known as biquadratic numbers or tesseractic numbers) is:1, 16, 81, 256, 625, 1296, 2401, 4096, 6561, 10000, ... (sequence A000583 in OEIS)The last two digits of a fourth power of an integer can be easily shown (for instance, by computing the squares of possible last two digits of square numbers) to be restricted to only twelve possibilities:00, 01, 16, 21, 25, 36, 41, 56, 61, 76, 81, 96Every positive integer can be expressed as the sum of at most 19 fourth powers; every sufficiently large integer can be expressed as the sum of at most 16 fourth powers (see Waring's problem).Euler conjectured a fourth power cannot be written as the sum of 3 smaller fourth powers, but 200 years later this was disproven with:958004 + 2175194 + 4145604 = 4224814.".
