Question 108918
Is this the problem?
{{{ln(x)+ln(3x)=12}}}
From the log rules,
{{{ln(a)+ln(b)=ln(ab)}}}
Then
{{{ln(x)+ln(3x)=12}}}
{{{ln(3x^2)=12}}}
{{{3x^2=e^12}}}
{{{x^2=e^12/3}}}
{{{x=sqrt(e^12/3)}}} and {{{x=-sqrt(e^12/3)}}}
x=232.92 and x=-232.92
Check your answers.
{{{ln(x)+ln(3x)=12}}}
{{{ln(232.92)+ln(698.76)=12}}}
{{{5.45+6.55=12}}}
{{{12=12}}}
True statement.
Good answer.
