The difference of their cubes is 4.
This is a nth term question. The formula for this is: n³ + 2 So, replace the n with 10: 10³ +2 = 1002
First, you can take out the common factor "x".For what remains (the factor other than "x"), you can use the formula for the difference of two cubes.
The formula for the sum of a series of cubes is as follows: 13 + 23 + 33 + ... + n3 = [n2*(n+1)2]/4 You may notice that this is the same as the square of the sum 1 + 2 + 3 + ... + n.
Yes, 64 = 43
