You need a big L to get the equivalence arrow.

Bob does not think there are any others ( he has a point ) and I can not find any others. Maybe that statement was too cautious.

hi Agnishom and bobbym,

What bobbym has said holds good whatever log base you are using providing all three logs are the same base throughout the equation.

Furthermore, as log is an increasing function I think bobbym's answer is the only one.

Bob

ps. also providing neither p nor q is equal to 1.

Hi;

I am getting:

Take the exponential of both sides.

There may be other solutions!

If Log p + Log q= Log (p+q)

Then what is the relationship between p & q?
