log1- log25=
natural log1-natural log8=
-----------------
logs are exponents, so subtraction means division
-----------
log(1) - log(25) = log(1/25) = log(0.04)
Then it's calculator work
log(0.04) =~ -1.39794
---------------------
ln is used for natural logs
ln(1) - ln(8) = ln(1/8) = ln(0.125)
=~ -2.07944
