comment Simplify expressions with Log
Perfect - that's exactly what I was looking for with the added benefit it can be applied in other situations too. Thanks!

comment Simplify expressions with Log
This looks very good. Is there any easy way I can allow multiple arguments for rule1, i.e. rule1 = Log[a_] + Log[b_] + Log[]... -> Log[a*b*...]?

comment Simplify expressions with Log
@Mr.Wizard - it works because it's shorthand for Simplify[Log[Exp[n Log[a] + m Log[b] - m Log[a + b] - n Log[a + b]]]] . So works perfectly for this expression; however, it won't work for more complex expressions. See the Prefix.

comment How to transform an expression using algebraical instead of pattern rules
@PinguinDirk yes that seems to return the same result as the ExpandAll statement. Seems much better. Might take a while to run against a quartic on my laptop. Will investigate a little further. I will also investigate Eliminate mentioned elsewhere. Thanks.

@chuy how would you expand that idea to discriminants?

comment How to transform an expression using algebraical instead of pattern rules
@b.gatessucks Yes, that's obvious. The point is that requires one to solve for k in the rule before using it. I am looking for an automated way of making these transformations.
