evaluating natural log expressions: ln sq rt e w/o calc  TOPIC_SOLVED

I need to evaluate the following without a calculator:

ln sq.rt.e (sorry I can't find notation for square root). Does this mean the natural log of e to the 1/2 power? :confused:

Yes, a square root is the same as a one-half power. For clarification, try here. :wink:

ok, so how about ln (1/sq.rt.e)?

would it be -1/2?
