how do you find the value of logarithms. Equations with logarithms on one side take the form of log b M n M b n. Log b c 1 log c b Logarithm change of base rule.
Rewrite the logarithmic equation in exponential form. Remembering this equivalence is the key to evaluating logarithms. The major exception is that because the logarithm of 1 is always 0 in any base ln1 0 l n 1 0.
Verify the data follow a logarithmic pattern.
This is called a natural logarithm. For other natural logarithms we can use the ln l n key that can be found on most scientific calculators. One the base and the number in the parenthesis are identical the exponent of the number is the solution to the logarithm. Verify the data follow a logarithmic pattern.
