If you're ready to learn How to solve a sum of cubes, keep reading!
So, to factor, I'll be plugging 3x and 1 into the sum-of-cubes formula. This gives me: 27 x3 + 1 = (3 x) 3 + 1 3 = (3 x + 1) ( (3 x) 2 − (3 x ) (1) + 1 2) = (3x + 1) (9x2 − 3x + 1) Content Continues Below

Since a is the cube root of the first term, we know a = x 3 3 = x . Likewise, since b is the cube root of the second term, we know b = 1 3 = 1 . Step 2. Write down the factored form. a 3 + b 3 = ( a +
The formula to find the sum of cubes of n natural numbers is S = [n 2 (n + 1) 2 ]/4, where n is the count of natural numbers that we take. For example, if you want to find the sum of cubes of 7
