Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Exponential Form
Exponential form expresses a number as a base raised to a power, represented as b^y = x, where b is the base, y is the exponent, and x is the result. This form is essential for understanding how logarithms work, as logarithmic statements can be converted into exponential statements to reveal the relationship between the base, exponent, and result.

Exponential Functions
Logarithmic Form
Logarithmic form is the inverse of exponential form, expressed as log_b(x) = y, meaning that b raised to the power of y equals x. This form is crucial for solving equations involving logarithms, as it allows us to find the exponent when the base and the result are known, facilitating the conversion between the two forms.

Logarithms Introduction
Change of Base Formula
The change of base formula allows for the conversion of logarithms from one base to another, expressed as log_b(a) = log_k(a) / log_k(b) for any positive k. This concept is important when dealing with logarithmic equations, as it enables simplification and calculation using more familiar bases, such as 10 or e, making it easier to solve logarithmic expressions.
