is there a way to get maple to perform simple logarithm manipulations i.e. ln(a*b^c)=ln(a)+c*ln(b) ? I've noodled around with the convert utility with no luck. I am trying to do a power law regression via the normal equation "showing my work". I have the answer using CurveFitting so I'm just trying to fill in the steps thanks

can I change the behavior of maple to not represent 1/sqrt(2) as sqrt(2)/2? I guess in a mathmatician's view this is a simplification, but not from an engineering standpoint. also, if I perform combine(sqrt(2)/(sqrt(m)*sqrt(k)),radical,symbolic) I get sqrt(2)*sqrt(1/m k) instead of the desired sqrt(2/(k*m))..is this related? I'm sure there is a nuance that I am not getting...

Using maple 10, when I store say a 15 x 1 matrix I get the placeholder (1..15 Vector[column], Datatype=anything....) When I close the document and open it back up, all af the data I typed in is gone. What's up with this?
