How do you solve #10^(4x-1) = 5000#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer VNVDVI Mar 2, 2018 #x=ln(5000)/(1ln(4))+1/4# Explanation: Apply the natural logarithm to both sides: #ln(10^(4x-1))=ln(5000)# #ln(10^(4x-1))=(4x-1)ln(10),# as the exponent property for logarithms tells us that #ln(x^y)=yln(x)#. #ln(10^(4x-1))=ln(5000)hArr(4x-1)ln(10)=ln(5000)# Solve for #x:# #((4x-1)cancelln(10))/cancelln(10)=ln(5000)/ln(10)# #4xcancel(-1+1)=ln(5000)/ln(10)+1# #(cancel(4)x)/cancel4=ln(5000)/(4ln10)+1/4# Answer link Related questions What is a logarithmic model?
