I have a measured value of 'A' (=5.20) and an associated standard error (=0.29).

I have a measured value of 'B' (=10.07) and an associated standard error (=0.65).

I need to report the difference in log-transformed values of these two quantities:

log(10.07) - log(5.20)

= 1.003 - 0.716

= 0.287

How do I calculate the standard error for this value?

I would greatly appreciate any suggestions. Thank you very much.
