Use the standard logarithm rules to simplify any natural logarithm expression. The pertinent rules in this matter are the division, multiplication, and exponent rules of logarithms. This often results in one logarithm being turned into many, for example, Ln(x/2) = Ln(x) - Ln(2).
Evaluate any natural logarithms with non-variable arguments. The Ln(2) from above would evaluate to approximately 0.6931.
Raise each term, including previously evaluated non-variable numbers, the the base "e."This simply means make all values in the expression an exponent of e. For example, from above, Ln(x) - 0.6931 = e^Ln(x) - e^0.6931.
Simplify the expression. Remove both the "e" and "Ln" portion of any term which contains both. Continuing from above: e^Ln(x) - e^0.6931 = x - e^0.6931. This resulting expression can be evaluated using standard algebraic manipulation and a calculator to solve for the value of "x."
