Here are the essential concepts you must grasp in order to answer the question correctly.
Logarithmic Functions
Logarithmic functions are the inverses of exponential functions and are defined for positive real numbers. The natural logarithm, denoted as ln(x), is particularly important in calculus and algebra, as it helps solve equations involving exponential growth or decay. Understanding the properties of logarithms, such as the product, quotient, and power rules, is essential for manipulating and solving logarithmic equations.

Absolute Value
The absolute value of a number is its distance from zero on the number line, regardless of direction, and is denoted as |x|. In equations, absolute values can create two separate cases to consider, as |x| = a implies x = a or x = -a. This concept is crucial when solving equations that involve absolute values, as it affects the solution set and requires careful consideration of both positive and negative scenarios.

Solving Exponential Equations
Solving exponential equations often involves isolating the exponential expression and applying logarithms to both sides of the equation. This process allows us to transform the equation into a linear form that can be solved for the variable. In the context of the given equation, understanding how to manipulate and solve for x after applying logarithmic properties is key to finding the correct solution.
