This math topic focuses on converting exponential expressions with the natural base \(e\) into logarithmic form. The problems are structured to help students apply the logarithmic identity \(\log_b a = c\) equivalently to \(b^c = a\), specifically using the natural logarithm base. Each question presents an equation in exponential form and asks for the equivalent logarithmic expression, offering multiple choices for students to select from. These problems help practice understanding and manipulating exponential and logarithmic relationships using \(e\) and develop skills in logarithmic conversions.
