Understanding Logarithmic Functions

The video tutorial explains how to convert exponential equations into logarithmic equations. It begins by establishing the equivalence between the two forms, highlighting the roles of the base, exponent, and number in each equation. The tutorial then demonstrates the conversion process using examples, emphasizing the special notation for natural logarithms (ln) when the base is e. The video concludes with a practical example, converting e^4 = x into its logarithmic form, ln x = 4.

What is the equivalent logarithmic form of the exponential equation b^a = n?
