The following question is really one of accuraccy of the HP48SX, specifically,
and the answer might not apply to other calculators:

To compute:

       log  a
          b

You can use:

       log  a
          n
       ------
       log  b
          n

Therefore, on the 48sx, you must use either:

       LOG a                      LN a
       -----            or:       ----
       LOG b                      LN b

        #1                         #2

So, my question is this: which is more accurate? #1, or #2? (does the
48 internally use LOG to compute LN, or vice versa?) Thanx.
