How do you solve log(x^3)=(logx)^3? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer bp Sep 11, 2015 x=1, 10^sqrt3, 10^-sqrt3 Explanation: log(x^3)= 3log x 3log x= (logx)^3 (log x)^3 -3logx =0 logx ( (log x)^2-3)=0 logx=0, (logx)^2 -3=0 log x=0 means x=1 and (logx )^2 -3=0 would mean log x=+-sqrt3, or x=10^sqrt3, 10^-sqrt3 Answer link Related questions What is a logarithmic model?
