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?

DonAntonio said:Sure. It's always true that [itex]n\log_ax=\log_a(x^n)\,[/itex] , so [tex]\log D-b\log K=\log D-\log K^b=\log\left(\frac{D}{K^b}\right)[/tex]

The purpose of separating the variables in A*log(b) is to make the equation easier to solve. By separating the variables, we can isolate and manipulate each variable individually, making it easier to find a solution.
To separate the variables in A*log(b), we use the properties of logarithms. We can rewrite the equation as log(b^A), and then use the power rule to separate the variables. This means we can take the exponent A and move it in front of the logarithm as a coefficient.
Separating variables in A*log(b) allows us to solve for specific values or relationships between the variables. It also allows us to manipulate the equation to find different solutions or simplify the problem.
Yes, it is possible to solve A*log(b) without separating the variables. However, separating the variables makes the problem easier to solve and can also provide more information about the relationship between the variables.
One limitation of separating variables in A*log(b) is that it can only be done if the base of the logarithm is positive. If the base is negative, the logarithm is undefined and cannot be separated. Additionally, separating variables may not always provide a unique solution for the equation.
