In Exercises 89–102, determine whether each equation is true or false. Where possible, show work to support your conclusion. If the statement is false, make the necessary change(s) to produce a true statement.ln x + ln(2x) = ln(3x)

Logarithms have specific properties that simplify expressions. Key properties include the product rule, which states that ln(a) + ln(b) = ln(ab), and the quotient rule, ln(a) - ln(b) = ln(a/b). Understanding these properties is essential for manipulating logarithmic equations and verifying their validity.

The natural logarithm, denoted as ln, is the logarithm to the base e, where e is approximately 2.718. It is commonly used in calculus and exponential growth models. Recognizing how ln interacts with exponential functions is crucial for solving equations involving ln.

To determine if an equation is true or false, one must verify both sides of the equation under the same conditions. This often involves substituting values or simplifying both sides to see if they are equal. If they are not, identifying necessary changes to make the equation true is a key skill in algebra.
