How do you solve #-log x = 4.176#? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models 1 Answer Alan P. Dec 7, 2015 #x~= 6.668xx10^(-5)# Explanation: #-log x = 4.176# #color(white)("XXX") rArr log x = -4.176# #color(white)("XXX")10^(-4.176) = x# therefore (using a calculator) #color(white)("XXX")x = 6.668xx10^(-5)# Remember #color(white)("XXX")log_b a = c# means #b^c = a# and #color(white)("XXX")#the default base (#b#) for #log# is #10# Answer link Related questions What is a logarithmic model?
