Question 268965
First we use the power rule to get
{{{log(5,x^3) - log(5,4) = log(5,16)}}}
next, when we subtract logs, we divide the information to get
{{{log(5,x^3/4) = log(5,16)}}}
third, eliminate the logs to get
{{{x^3/4 = 16}}}
multiply by 4 to get
{{{x^3 = 64}}}
taking a cube root we get
 {{{x = 4}}}
