For example, consider the equation To solve for we use the division property of exponents to rewrite the right side so that both sides have the common base, Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for: For any algebraic expressions and any positive real number. Using the common log. When we plan to use factoring to solve a problem, we always get zero on one side of the equation, because zero has the unique property that when a product is zero, one or both of the factors must be zero. For example, consider the equation To solve this equation, we can use the rules of logarithms to rewrite the left side as a single logarithm, and then apply the one-to-one property to solve for. Note, when solving an equation involving logarithms, always check to see if the answer is correct or if it is an extraneous solution. Keep in mind that we can only apply the logarithm to a positive number. In approximately how many years will the town's population reach.
