50g prefers LN instead of LOG during symbolic solve

[fire_for_effect]

after doing a survey of multiple mathematic programs on the PC, I agree with Tim on the basis that even though the programs will show log they are in fact referring to LN. So I suppose I can chalk the rest of it up to naivety since I haven't used cas systems much before this and the confounding way that Microsoft's mathematics program ( free, btw) refers to ln as log.
