#log_2(x+1)=log_4(x^2-x+4)# What is the value of x? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Cesareo R. Aug 3, 2017 #x=1# Explanation: Equivalently we have #(log_2(x+1))/(log_4 (x^2-x+4)) =( (log_e(x+1)/log_e 2))/( (log_e(x^2-x+4)/log_e4)) = 2(log_e(x+1)/ (log_e(x^2-x+4)))=1# or #2log_e(x+1)=log_e(x^2-x+4)# or #(x+1)^2=(x^2-x+4)# or #2x+1=-x+4# or #3x=3# or #x = 1# Answer link Related questions What is a logarithmic model?
