How do you solve #ln y = 2x + 4#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Alvin L. Mar 4, 2018 #y=e^(2x+4)# Explanation: Assuming the goal is to isolate #y#, we can do so by raising both sides as a power of #e#, cancelling the natural logarithm: #e^ln(y)=e^(2x+4)# #y=e^(2x+4)# Answer link Related questions What is a logarithmic model?
