applying logarithms into a complicated function can make the function much easier.  for example:

y= [x^(3/4)√ (x + 1)]/(3x + 2)^5

apply log to both sides

lny = 3/4lnx + 1/2lx(x + 1) - 5ln(3x + 2)

all we gotta do now is add and subtract which is much easier than the original one.

There's a good entry about logarithms in Wikipedia. It's got a paragraph about their history if you scroll down.

hi good friends!
I searched the web for a document that contain history of logarithm but didn't find an iteresting thing!
Is there a savier?
