 What is Log? [2/26/1995]

What is 4 to the half power, and what is log?
 2^x = 8 [05/27/2003]

How can I solve for x in the equation 2^x = 8?
 Comparing Very Large NumbersWhich Is Bigger? [12/01/2004]

How do you decide which large number is greater? For instance, how do
you know whether 9!^(9!^9) is greater than 10^(10!^10)?
 Decimal Exponents [03/19/1999]

Find x^y, where y is a decimal, without using a calculator.
 Etymology of 'Logarithm' [03/19/1999]

How does the term 'logarithm' relate to the terms 'exponent' and 'knots',
and to nautical logbooks?
 John Napier [06/17/1998]

Why was John Napier's discovery of logarithms a great contribution to the
field of mathematics?
 A Logarithmic Equation [08/06/1998]

How do you solve A*2^(x/y) = B for x using a base 2 logarithm?
 Logarithmic Problem [2/22/1995]

Can you help me solve this: log 3^x = 6 + (1/2)log 9^x?
 Logarithmic Scales [12/13/1998]

Why do we use logarithmic scales and in what applications do they appear?
 Logarithms [11/2/1994]

Can you explain exactly what a logarithm is?
 Logarithms before 1965 [02/08/1999]

Could you tell me how logarithms were used before the year 1965?
 Logarithms in Bases Other Than 10 [03/28/1998]

What methods are available for solving logarithms in a base other than
10?
 Logarithms: Solving for T [01/30/1998]

3.5 = (1.12)^T. We can't remember how to solve for T
 'Log' Button [01/29/1998]

We have been using the 'log' button on our calculators to solve problems
involving compound interest. What does that button do?
 Long Numbers and Logarithms [10/11/2002]

How many terms are there in (12)^(214)? How about (123)^214?
 Measurements on a Logarithmic Scale [11/21/1998]

What kinds of measurements are done on a logarithmic scale? What physical
properties make a logarithmic scale more appropriate?
 Natural Logs [12/20/1997]

I need to understand natural logs. Could you please explain them in the
simplest terms possible?
 Origin of the Term Logarithm [10/27/1999]

Where does the term logarithm come from?
 Slide Rules [03/13/1999]

Can you help me learn how to use a slide rule?
 Solving Logarithms with the Quotient Rule [11/11/1998]

Can you help me solve this logarithm problem for x? I think you need to
use the quotient law.
 Taking the Logarithm of Zero [08/11/2004]

Why is log(0) undefined?
 Why Do We Learn Logarithms? [02/28/2005]

I am currently studying logarithms in school and I was wondering what
the point of them is. Will we ever use them when we grow up, and how
are they used in real life?
 Why Use a Logarithmic Scale to Display Data? [01/26/2008]

I read that log scales help you see data when you are looking at
values that range largely. I also read that if the ear did not hear
logarithmically we would only hear very loud sounds. Can you help me
understand these two statements?
