How do you solve #log4x - log16 = 1#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Noah G Apr 14, 2016 Use the log rule #log_an - log_am = log_a(n/m)# Explanation: #log_10((4x)/16) = 1# #(4x)/16 = 10^1# #4x = 10(16)# #4x = 160# #x = 40# Hopefully this helps!
