Derivative:
This derivative represents the rate of change of the original function. The calculation follows standard differentiation rules as shown in the step-by-step solution below.
Logarithmic functions like log_a(x) are related to exponential functions, making them candidates for applying the Power Rule. The base 'a' in log_a(x) requires a specific approach to differentiation.
💡 Why this works: The Power Rule applies to functions of the form log_a(x), where 'a' is the constant base. The structure of log_a(x) allows us to differentiate it by first converting it into a form suitable for the Power Rule, which simplifies the differentiation process.
To differentiate log_a(x), we use the Power Rule for logarithms, which simplifies the process to the derivative of log(x) with base 'a'.
💡 Why this works: By using the derivative formula for logarithms, we know that d/dx[log_a(x)] = 1/(x * ln(a)). This result comes from applying the Power Rule, which deals with the rate of change of the logarithmic function.
After applying the Power Rule, the derivative becomes d/dx[log_a(x)] = 1/(x * ln(a)), where ln(a) is the natural logarithm of the base 'a'.
💡 Why this works: The final derivative, 1/(x * ln(a)), is the correct form because it reflects the rate of change of log_a(x) with respect to x. We ensure accuracy by confirming that the application of the Power Rule is correct and the logarithmic base is properly considered.
