If #5^(x+2)=4#, find #x#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Shwetank Mauria Mar 14, 2017 #x=-1.1386# Explanation: As #5^((x+2))=4# #(x+2)log5=log4# i.e. #x+2=log4/log5=0.60206/0.69897# i.e. #x+2=0.8614# and hence #x=0.8614-2=-1.1386# Answer link Related questions What is a logarithmic model?
