How do you solve 3^(2x+1)=5^200? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer P dilip_k Apr 30, 2016 =>x=(200log5-log3)/(2log3) Explanation: 3^(2x+1)=5^200 Taking log on both sides we have log(3^(2x+1))=log(5^200) =>(2x+1)log(3)=200log(5) =>2xlog3+log3=200log5 =>2xlog3=200log5-log3 =>x=(200log5-log3)/(2log3) Answer link Related questions What is a logarithmic model?
