Discussion Overview

The discussion revolves around the interpretation and manipulation of expressions involving exponents and variables, specifically focusing on the notation like x^3x+2. Participants explore the mathematical properties of such expressions and seek resources for further understanding.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses confusion about the notation x^3x+2 and seeks resources related to such exponents.
  • Another participant comments on the growth behavior of functions like x^x, mentioning related identities without providing specific details.
  • A third participant reflects on their understanding of the notation, indicating that it can be analyzed using basic algebraic principles.
  • A later reply critiques the initial notation, suggesting that it should be interpreted according to PEMDAS rules, parsing it as (x^3 · x) + 2.

Areas of Agreement / Disagreement

The discussion contains varying interpretations of the notation and its implications, with no consensus reached on a definitive understanding or approach to the problem.

Contextual Notes

There are limitations regarding the clarity of notation and the assumptions underlying the interpretation of the expressions discussed. The discussion does not resolve the mathematical steps involved in analyzing the notation.

When one was reading some review books for engineering mathematics one has come across that kind of notation, below, and where to find books or materials that deals with these kinds of exponents, they look like this>> x^3x+2.

This must be the most unintentionally hilarious post I've ever seen on PF.

Well from what I know functions like x^x simply grow very quickly, there are some identities related to the function.

i know right. I didn't quite get it but after some analysis though its easy.:) also I'm not referring to higher mathematics for this one, this was pure algebra under the laws of exponent. ah thanks for the help by the way.

You might want to work on your notation. According to the PEMDAS rules, that string parses as: ##( x^3 \cdot x ) + 2##
