next question on simplify

[Hans S.]

Hi, simple Simon asks:
what is the idea behind the following beheavior?
solve(8^(n+2)-8^(2*n)=240,n) --> (2/3, (ln(15)+2*ln(2))/(3*ln(2)) -- ok, that's fine, next step

simplify(ln(15)+2*ln(2))/(3*ln(2)) --> ln(15)+2*ln(2))/(3*ln(2) -- oh, that's not so fine.

What makes the prime acting like this? simplify(ln(15)+2*ln(2)) works well and says ln(60).

Beheavior like this in algebraic or textbook mode, simplify maximum, non, minimum setting, and I also tried all the other checkboxes etc. And yes, I used enough brackets, even if I forgot some here.

As I wrote: what is the idea behind? Shouldn't the maximum level for simplify just say (on the "solve" level) "2/3, ln(60)/3*ln(2)"? and leave the less elaborated answers to the other level(s)?
Or is this just an issue with the "/"? Or am I simply stupid and didn't see the wood for the trees?

Thanks
Hans
