5 ln e8 – ln e7
---------
Nothing to solve, just simplify some.
I assume you mean
5ln%28e%5E8%29+-+ln%28e%5E7%29
= 5*8 - 7
= 33

I'm assuming you mean,5%2Aln%28e%5E8%29-ln%28e%5E7%29??
5%2Aln%28e%5E8%29-ln%28e%5E7%29=40%2Aln%28e%29-7%2Aln%28e%29
5%2Aln%28e%5E8%29-ln%28e%5E7%29=40%2A1-7%2A1
5%2Aln%28e%5E8%29-ln%28e%5E7%29=highlight%2833%29
