# Thread: natural logarithmic rules of the form ln(a-c)

1. ## natural logarithmic rules of the form ln(a-c)

Hi,

Is there any way for me to simplify the expression below? Preferably with theta isolated outside of the natural log?

Any help would be much appreciated!

2. ## Re: natural logarithmic rules of the form ln(a-c)

I don't think so.

The only thing you could do is to factorise the expression, but that still won't isolate theta.

Even then, $h^{\theta} - g^{\theta}$ can't really be factored (unless $\theta$ is an integer).

Thanks for helping me confirm that there's no further simplification possible.
