Here are the essential concepts you must grasp in order to answer the question correctly.
Change of Base Theorem
The Change of Base Theorem allows us to express logarithms in terms of logarithms of a different base. Specifically, for any positive numbers a, b, and c (where a and b are not equal to 1), the theorem states that log_b(a) can be rewritten as log_c(a) / log_c(b). This is particularly useful for converting logarithms to a base that is more convenient for calculation, such as natural logarithms.

Natural Logarithm
The natural logarithm, denoted as ln(x), is the logarithm to the base e, where e is approximately equal to 2.71828. Natural logarithms are widely used in mathematics, particularly in calculus and exponential growth models. They have unique properties, such as ln(e) = 1 and ln(1) = 0, which make them essential for solving equations involving exponential functions.

Logarithmic Properties
Logarithmic properties are rules that govern the manipulation of logarithms. Key properties include the product rule (log_b(xy) = log_b(x) + log_b(y)), the quotient rule (log_b(x/y) = log_b(x) - log_b(y)), and the power rule (log_b(x^k) = k * log_b(x)). Understanding these properties is crucial for simplifying logarithmic expressions and solving logarithmic equations effectively.
