How do you solve #2/3e^(4x)+1/3=4#? Precalculus Properties of Logarithmic Functions Natural Logs 1 Answer Noah G Aug 7, 2016 Let's start by isolating the #e^(4x)#. #2/3e^(4x) = 4 - 1/3# #2/3e^(4x) = 11/3# #e^(4x) = (11/3)/(2/3)# #e^(4x) = 11/2# #ln(e^(4x)) = ln(11/2)# #4x(ln(e)) = ln(11/2)# #4x = ln(11/2)# #x = 1/4ln(11/2)# Hopefully this helps!
