06 February 2013 Let x = e^0.0075

Log x = log e^0.0075

Log x = 0.0075 * log e

Log x = 0.0075 * 0.4343

Log x = 0.0032

x = Antilog 0.0032

x = 1.0075

07 February 2013 Natural Logarithm is base "e".

You might be looking at tables for base 10.

The above calculation which I have done is w.r.t base 10.

08 February 2013 log (e) 1.0667
= log (10) 1.0667/log (10) e
= 0.028042/0.4343
= 0.064568

Hope it is clear now.

Note - the text in brackets () represents the base.

08 February 2013 log of 1.0667 to base 10. I have used MS-excel, you can use logarithm tables to get the answer.
