This algebra 2 math tutorial from NutshellMath offers help with various properties of natural logarithms, as well as solving natural logarithmic and exponential equations. Natural logarithms are logarithms with a base of e, and are important algebraic operations with special properties.


As introduced in the tutorial, the product property of natural logarithms states that the natural log of a product of two factors is equal to the sum of the natural logs of each of the factors. The quotient property of natural logarithms states that the log of a quotient of two terms is equal to the difference of the natural log of the dividend and natural log of the divisor. The power property of natural logarithms states that the natural log of a term raised to a power is equal to the product of that power and the natural log of the base.

These properties are important in manipulating and evaluating natural logarithmic expressions and equations. The examples in this tutorial show how to use properties of natural logarithms to write expressions containing multiple natural logs as a single natural logarithmic expression.

To solve a natural logarithmic equation, the equation can be converted to exponential form first, to remove the natural log, and the resulting equation solved for the variable. Natural logs can also be used to solve exponential equations, which contain a term of e raised to a multiple of x. To solve, first isolate the exponential term and then take the natural log of both sides. Algebra can then be used to solve for the variable.

Natural logarithms and their properties are powerful tools to use for solving algebraic equations.
