Discussion Overview

The discussion centers around alternative expressions for the mathematical term (a+b)^c, specifically seeking simpler forms without using square roots. Participants explore various approaches and examples to illustrate their points.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant asks for a simpler expression for (a+b)^c, noting that a^c + b^c is not equivalent.
  • Another participant suggests that they are unaware of any simpler form, referencing the complexity of expanding (a+b)^100 as an example.
  • A different participant proposes rewriting (a+b)^c as a^c * (1 + b/a)^c, indicating this is useful when working over the reals.
  • One participant clarifies that the goal is not necessarily to simplify but to avoid complexity, expressing appreciation for the previous suggestion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a simpler expression for (a+b)^c, and multiple viewpoints regarding the complexity and utility of different forms remain present.

Contextual Notes

Some assumptions about the context of the expressions, such as the domain of real numbers, are mentioned but not fully explored. The discussion does not resolve the question of simplification.

Who May Find This Useful

Mathematicians, students, or anyone interested in algebraic expressions and their transformations may find this discussion relevant.

what is another way to form (a+b)^c to another simple expression?
like for example a^c+b^c doesn't work because its not eqivalent to (a+b)^c
(without using squareroot)

im know of no way that is simpler. just look at the example of (a+b)^100.

how simple is that? or just try to simplify (a+b)^3.
 
I occasionally find it useful to write it as a^c * (1 + b/a)^c -- of course only when working over the reals.
 
it doesn't have to be simpler, just not so complicated. thanks CRGreathouse, that helps,
