Abstract: Inspired by the fact that the sum of the cubes of the first \$n\$ naturals is equal to the square of their sum, we explore, for each \$n\$, the Diophantine equation representing all non-trivial sets of \$n\$ integers with this property. We find definite answers to the standard question of infinitude of the...

Mar 13, 2015 · Greatest Common Factor. Always begin by factoring out the greatest common factor (GCF) if it is anything other than 1. \( 15x^3-35x^2-30x \Longrightarrow 5x ( 3x^3-7x-6 ) \) Look at the number of terms If there are two terms. Difference of two squares, \( a^2-b^2 = (a-b)(a+b) \) Sum of two squares, \( a^2 + b^2 \) is prime. Sum of Cubes Formula. The other common factoring formula that you should know is very much similar to the earlier one with a single difference of sign. Here, is a quick representation of how the sum of cubes formula can be given in mathematics. Look at the formula given carefully.

Intro to Sum and Differences of Cubes. 2.08mins Sum of Cubes Examples May 15, 2013 · Ok. What? Let’s take an example of the four existing narcissistic cubes: 153 = 1^3 + 5^3 + 3^3 370 = 3^3 + 7^3 + 0^3 371 = 3^3 + 7^3 + 1^3 407 = 4^3 + 0^3 + 7^3. In these cases, each digit is cubed because there are three digits in the number. Then, those cubed numbers are added together to produce a sum equal to the original number. For example, if A is a matrix, then sum(A,[1 2]) is the sum of all elements in A, since every element of a matrix is contained in the array slice defined by dimensions 1 and 2. example S = sum( ___ , outtype ) returns the sum with a specified data type, using any of the input arguments in the previous syntaxes.

A necessary condition for to equal such a sum is that cannot equal 4 or 5 modulo 9, because the cubes modulo 9 are 0, 1, and −1, and no three of these numbers can sum to 4 or 5 modulo 9. It is unknown whether this necessary condition is sufficient.

Perimeter-magic cubes. The cubes shown in this section represent another branch of magic objects. Here the objective is to number the outline (perimeter) of the object in such a way that all lines or surfaces sum to a constant. Just as magic squares, cubes, etc are classified into orders, so are perimeter magic objects.
