How do you solve 3 log x=1.5? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Alan P. Dec 21, 2015 x=sqrt(10) Explanation: 3log(x) = log(x^3) 10^(log(x^3)) = x^3 So if 3log(x) = 1.5 then color(white)("XXX")x^3= 10^(1.5) = 10^(0.5)xx10^(0.5)xx10^(05) color(white)("XXX")rarr x= 10^(0.5) = sqrt(10) Answer link Related questions What is a logarithmic model?
