A*log(b), Separating the two variables

AI Thread Summary
The equation log(D) - b*log(K) = b*log(z) - log(c) can be manipulated using logarithmic properties to express it as log(D/K^b). However, this transformation results in a function that includes b, contradicting the original request to isolate D and K on one side. The discussion highlights the challenge of separating the variables as desired. Participants express curiosity about finding a solution that meets the specific requirement. Ultimately, isolating D and K while keeping the other variables separate remains unresolved.

Hi!

I have a problem with the following equation:

log(D)-b*log(K) = b*log(z)-log(c)

I would like to get D and K on one side of the equal to sign, so that:

f(D,K) = g(b, c, z)

Is this possible?

Sure. It's always true that n\log_ax=\log_a(x^n)\, , so \log D-b\log K=\log D-\log K^b=\log\left(\frac{D}{K^b}\right)

But this gives the function in the sense, f(D,K,b)=g(b,z,c), contrary to what the OP is asking.

I couldn't find a way to get only D and K on one side of the equality and rest of the variables on the other side, so I'm really curious about this one...
 
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...
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...
