Also, you may want to be able to calculate natural logarithms without calculator. I will tell you a method that I use: since \exp 3 \approx 20, you can take \log 20 \approx 3. Hence, to calculate \log n in practical applications, first calculate \log20 n, then multiply it by 3. The first is called logarithmic form and the second is called the exponential form. Remembering this equivalence is the key to evaluating logarithms. The number, b, is called the base. Example 1 Without a calculator give the exact value of each of the following logarithms.
