How to Solve Exponents that also has a variable with it

AI Thread Summary
The discussion centers on solving exponents with variables, specifically the notation x^3x+2. Participants note that functions like x^x grow rapidly and mention related identities. There is a suggestion to improve notation for clarity, as the expression can be misinterpreted according to PEMDAS rules. Resources for understanding these types of exponents are also sought. Overall, the conversation emphasizes the importance of proper notation in algebraic expressions.

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##
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
