show that
(a+b+c)^3=a^3+b^3+c^3
implies that
(a+b+c)^5=a^5+b^5+c^5
(a+b+c)^3=a^3+b^3+c^3
implies that
(a+b+c)^5=a^5+b^5+c^5
The discussion revolves around proving the algebraic identity that states if \((a+b+c)^3 = a^3 + b^3 + c^3\), then it leads to \((a+b+c)^5 = a^5 + b^5 + c^5\). The subject area is algebra, specifically focusing on polynomial identities and their implications.
The discussion is ongoing, with some participants suggesting numerical examples to illustrate the identities, while others emphasize the need for a formal proof. There is no explicit consensus on the approach to take yet.
Participants note that numerical verification does not constitute a proof, highlighting the need for a more rigorous approach. There is an implicit understanding that the original poster may need to clarify their attempts or reasoning further.
AngeloG said:The first step you could do is put in numbers and verify it works numerically =).
Let's say
x * y^2 = x * y * y
x = 3, y = 2
3 * 2^2 = 12. (3 * 4 = 12)
3 * 2 * 2.
3 * 2 * 2 = 3 * 4 = 12
3 * 2 = 6 -> 6 * 2 = 12.
Thus, they are the same since they end up with the same answer =).
