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?
