LN computes the logarithm in the natural base e, which has the approximate value 2.7182818. Typing the formula "=LN(100)" gives the result 4.6051702. The inverse mathematical operation is the exponentiation function, which raises the constant e to a specified power. Its syntax is "=EXP(x)". For example, the formula "=EXP(4.6051702)" outputs the number 100. The two expressions can be combined as such: "=LN(EXP(3))". The result of this expression is 3.
