assuming you mean [tex]ln(e)ln(x)+ln(e)ln(x^2)=2ln(8)[/tex]

remember that ln(e)=1

also remember that [tex]ln(a^b)=b(ln(a))[/tex]

also that if [tex]ln(a)=ln(b)[/tex] then a=b


so

[tex]ln(e)ln(x)+ln(e)ln(x^2)=2ln(8)[/tex]

[tex](1)ln(x)+(1)ln(x^2)=2ln(8)[/tex]

[tex]ln(x)+2ln(x)=2ln(8)[/tex]

[tex](1+2)ln(x)=2ln(8)[/tex]

[tex]3ln(x)=2ln(8)[/tex]

[tex]ln(x^3)=ln(8^2)[/tex]

[tex]x^3=8^2[/tex]

[tex]x^3=64[/tex]

[tex]x=\sqrt[3]{64}[/tex]

[tex]x=4[/tex]
