How do you solve #3log_3 4a=3#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Noah G Jun 9, 2016 #log_3(4a)^3 = 3# Use the rule #alogn = logn^a# #log_3(64a^3) = 3# Recall that if #log_a(n) = x#, then #a^x = n# #64a^3 = 27# #a^3 = 27/64# #a = root(3)(27/64)# #a = 3/4# Hopefully this helps!
