I am taking Algebra II (natural logarithm) Please show me how to write "ln 100=4.61" in exponential form. Learn this rule: The natural logarithm equation ln(A) = B is equivalent to the exponential equation: A = eB -------------------------- Therefore follow the above rule with A = 100 and B = 4.61 So the natural logarithm equation ln 100 = 4.61 is equivalent to the exponential equation: 100 = e4.61 EDwin
